She could be considered a poster child for anyone who's ever felt overshadowed by a sibling. But Ashlee Simpson's huge moment came not too long after her sister's.
Ashlee burst onto the music charts in 2004, five years after her older sister Jessica Simpson solidified herself as one of the teen pop icons of the late '90s.
When Jessica's star rose in 1999, Ashlee worked as her backup dancer?, and also appeared in TV ads. She also picked up acting roles in Seventh Heaven, Malcolm in the Middle and the movie The Hot Chick.
Things really picked up for Ashley when she landed her own reality show, a spin-off from Jessica's series with then-husband Nick Lachey, Newlyweds, and used it as a vehicle to launch her debut album Autobiography.
While Jessica gave us Celine Dion-style ballads and poppy bops, Ashlee set herself apart with a grungier aesthetic (read: black hair and lots of eyeliner) and sound.
Autobiography was a major success, producing hits like Pieces of Me and Shadow that quickly embedded themselves in the canvas of 2000s pop culture.
Led by the lyrics "living in the shadow/of someone else's dream"?, the latter track was assumed to be about Ashlee feeling overshadowed by her sister. But she confirmed that wasn't the case at all.
"It's really about dealing with myself ... finding my identity and saying, 'OK, you know, this is who I am, you know, imperfections and all, and I love myself for me'."
Although 2004 brought her huge success, it also saw Ashlee face humiliation and public scrutiny.
During an episode of Saturday Night Live, her performance hit a hurdle when pre-recorded vocals began to play over the wrong backing music.
Ashlee resorted to dancing an awkward jig to fill the uncomfortable 30-second silence before the show cut to commercials.
The incident left viewers convinced she'd lip synced the first song of her set, Pieces of Me, as the pre-recorded vocals of that song had then begun playing over the music for her second song, Autobiography.?
Later in the episode, a clearly mortified Ashlee said her band has 'started playing the wrong song' and she 'didn't know what to do.
Then, weeks after the episode aired, she blamed the incident on "severe acid reflux?", claiming this had led her dad to suggest she use a backing track just in case.
It was several years before Ashlee publicly addressed her infamous SNL performance. ?In 2018, she claimed it had made her "a better person".
"Things in life happen to you and they make you stronger and they make you a better performer, a better person. I think things like that build your character and your strength and it's how you handle them," she told E!
Though many believed the flubbed performance would mark the end of Ashlee's career, that wasn't the case at all.
She released a second album, I Am Me, in 2005, ?with her third coming in 2008.
Ashlee ¨C pictured with Jessica in 2014 ¨C also continued to land acting roles, including in the TV reboot of Melrose Place.
She also branched out into theatre, portraying Roxie Hart in productions of Chicago in the West End? and Broadway.
A?s far as her personal life is concerned, Ashlee has been married twice and has three children.
Her first husband was Fall Out Boy frontman Pete Wentz.
The pair announced their engagement in April 2008, ?married in May, and welcomed a son, Bronx, in November that same year. Ashlee filed for divorce from the musician in 2011.
She began dating Evan Ross, the son of iconic musician Diana Ross, in 2013, and they married the following year.
The couple, pictured, share a daughter, Jagger, and son, Ziggy.
?In the great Simpson sister tradition, Ashlee and Ross also had a reality show of their own, titled Ashlee + Evan, in 2018, with six episodes in total.
She was the wealthy socialite and villainous character who got in the way of Fran Fine's pursuit of Maxwell Sheffield.
Who could forget C.C. Babcock, a much-loved original character from the hit '90s sitcom, The Nanny.
Played by American actress Lauren Lane, C.C. Babcock remained on the show for the show's entire six-season run.
Though she appeared in one of the most popular TV series of all time, Lauren retired from acting two years after the show ended in 1999.?
Before landing the role of C.C., Lane (who was born Laura but changed it as another actress named Laura Lane was signed on in the Screen Actors Guild) had already appeared in a string of shows, including Positive I.D., Nervous Ticks, Hunter, and L.A. Law.
Her character? in The Nanny, who is hopelessly in love with Mr Sheffield, was often the butt of cruel jokes throughout the series.
Speaking to The Chicago Tribune in 2021, Lane revealed she had a hand in reinventing C.C.'s image in later seasons.
"C.C. was just getting eviscerated every single week," she said.
"So it was maybe season 3, I went to the producers and writers and said, 'Listen, it's not going to be fun anymore if we just see her getting beat up. Is there some way you can add in some aspect of ¨C she doesn't have to win, she can still lose, but maybe she sees it coming a little better?'"
This led to C.C. and the? butler Niles eventually marrying in the final season of the show.
Once The Nanny stopped airing, Lane's time in Hollywood also ended.
The actress, then aged 40, was a single mum and thought she'd struggle to land roles.?
"This was my headspace: I don't think anything's going to happen for me because I'm infinitely recognisable from this show that was on for a long time. They don't want to hire you for a while because everyone knows you as C.C," she told the publication.
Instead of sticking around in Los Angeles, ?Lane moved to Texas and began teaching at a university in theatre and dance.
Lane's last official acting credit was on The Nanny in 1999.
She did, however, reunite with some of the cast in a 2004 TV special.
Now aged 62, Lane? remains active on social media and still teaches at Texas State University full-time.
I take thee¡ Rachel
Helen Baxendale's story arc in Friends gave us one of the most iconic moments of the entire series, when Ross uttered the wrong name during his wedding.
The British actress, who played Ross's wife Emily Waltham for their very short-lived marriage, starred in 14 episodes between 1998 and 1999.
Baxendale's arrival on the scene kick-started a famous storyline on the hit '90s sitcom ¨C but despite the show's popularity, it seems the actress didn't exactly get on with her castmates.
The show's producers knew it would be tough for viewers to like the character of Emily, as she got in the way of Ross and Rachel's beloved "will they, won't they?" romance.
However, they had problems from the get-go.
According to producer James Burrows, who directed several episodes of Friends, Baxendale presented quite a challenge for the rest of the cast.
"She was nice, but not particularly funny," Burrows wrote in his book Directed by James Burrows.
"Schwimmer had no one to bounce off. It was like clapping with one hand."
He added: "In sitcoms and any type of romantic comedy, the funny is just as important as the chemistry. We discovered that any new girlfriend for Ross needed to be as funny as Rachel."
Burrows claimed the show might have wanted to "recast" Baxendale, but they kept her on as Emily due to "tight shooting deadlines".
Her character was later written out of the series after Emily and Ross's marriage ended.
According to Baxendale herself, though, she wasn't too worried about this.
She was pregnant by the time her storyline ended and needed to leave anyway.
"I had a little glimpse of what fame holds, and I decided it held a load of nothing," she told The Daily Mail in 2012.
"It contained nothing that mattered. Some people can deal with that well; it sits on their shoulders fine. But it wasn't for me. Friends was great fun, but I was just there so they could make some funny jokes about England. And I was also expecting, and you have to be thin out in America."
Since Friends, Baxendale has continued to work steadily in the UK.
She went on to appear in 33 episodes of Cold Feet between 1997 and 2003 and nabbed guest spots in shows including Law and Order: UK, Poirot and Cuckoo.
Her most recent acting credit was as Meggie McGregor between 2020 and 2022 in the series Noughts + Crosses, and she lent her voice to the 2023 podcast series The Sisters.
She lives in London with her partner, director David L Williams, and the couple share three children.
When the cast of Friends and many guest stars reunited for a one-time special on HBO in 2021, Baxendale did not make an appearance.
Born Tara Leigh Patrick, the world knows this blonde bombshell as Carmen Electra.
The model, singer and TV personality was once the "it girl" of the late '90s and noughties thanks to her appearances in Playboy and a stint on Baywatch.
Electra began her career as a dancer at an amusement park, before being discovered by pop legend Prince after she auditioned for a girl group that was set to be signed by his label.
Electra, who played lifeguard Lani Mackenzie for two seasons on the hit show, soon earned similar fame and notoriety as her co-star Pamela Anderson. Electra was touted as Anderson's replacement as the actress looked to retire for the show.
"I knew that she was leaving, so I think a big cast was brought in because it was like, Wow, Pam's leaving. How are we going to make up for it? She is Baywatch," Electra told Vanity Fair.
After winning fans for donning the iconic red swimsuit, Electra became a frequent guest star on spoof and comedy movies including Scary Movie, Epic Movie, Disaster Movie and Starsky & Hutch.
The parody films soon became her bread and butter.
Speaking to Vanity Fair in 2023, Electra said it transformed her image.
"What Scary Movie did was on another level," she said of the 2000 film, where she played Drew Decker.
"It changed something for [people who thought] maybe I was stuck up. We never knew it would be a number one movie."
Electra's Playboy appearances are also something of a legend.
She was featured in the magazine around the world no less than 44 times after becoming a global superstar.
She worked just as hard on her movies, with the actress being credited in over 40 films.
During her time in the spotlight, Electra was known for a handful of famous romances: including a brief fling with Prince, a relationship with Simon Cowell and an engagement to Korn guitarist Rob Patterson.
Over the past two decades, Electra made the move from films to TV shows and has guest starred in the likes of Jane the Virgin,? 90210, Suburgatory and the short-lived Joey.?
Now 51, Electra is still making appearances in films (her last credit was in the 2023 movie Good Burger) and has pivoted to modelling.
She featured in a campaign for Kim Kardashian's brand Skims and collaborated on a collection with an Aussie clothing brand.
Reflecting on her new era and continued popularity, the actress-turned-model told Vanity Fair: "It's so very sweet."
"My philosophy has been, Let's stay here in a balanced place of gratitude because not everything works¡You have an ego, and it will kill you."
Best known for his role as Sayid Jarrah in the television series Lost (2004¨C2010), Naveen Andrews has been rather quiet recently.
His latest role was in the 2022 television series, The Cleaning Lady, playing Robert Kamdar for two episodes.
The actor's climb to success was no walk in the park, however, with substance abuse issues and a high school controversy being part of his story.
At age 18, he moved into the home of his maths teacher, Geraldine Feakins, 30. The pair later welcomed a child, Jaisal.
Andrews broke into the industry in 1991, acting in his first film, London Kills Me, followed by the BBC's mini-television series, The Buddha of Suburbia.
Long before we saw him in Lost, Andrews began struggling with drug and alcohol abuse, telling the Canadian Press of the damage it had.
"I'd basically, virtually, killed my career in England. I used to drink and do drugs and whatever, and in all fairness, they (British producers) had to deal with that," said Andrews.
At the time, he was just keeping it all together and had replaced heroin with alcohol while he was working. In 1997, he collapsed on set, requiring medical attention, he then checked into rehab and has been sober since.
The actor told The Guardian that he doesn't want to, "dwell on it," adding, "It's a daily struggle," he says. "But one that I want to keep struggling along."
Andrews moved to the USA, hoping for a clean slate.
