It's hard to think about the hit '90s show without singing the iconic theme song "I'll Be There For You" by The Rembrandts.
The popular show aired for 10 successful seasons, beginning in 1994, and made all of it's six stars unforgettable.
Let's take a look at where they are today and what happened to some of the most popular guest stars too.
Then/Now: Jennifer Aniston
Jennifer Aniston is the highest-profile former cast-member by a mile, mostly due to her being dumped by Brad Pitt for Angelina Jolie. Her relationship drama aside, Jen has also starred in a string of big-budget films, some successful, some not so much, including "Derailed" (bomb), "The Break Up" (hit), "Friends With Money" (bomb), "He's Just Not That Into You" (meh), and most recently, "We're the Millers" (hit). She is currently engaged to fellow actor Justin Theroux.
Then/Now: Anna Faris
Anna Faris got her big break with her recurring role in the last season of "Friends," and her career has been on a roll ever since. She has guest-starred in the HBO hit "Entourage," and has starred in films like "My Super Ex-Girlfriend," "The House Bunny" (which she also produced), and "Observe and Report" with Seth Rogen.
Then/Now: Paul Rudd
After his recurring role as Phoebe's husband Mike Hannigan on the show, Paul Rudd has found leading-man success on the big screen and has appeared in mega-hits like "Knocked Up," "Forgetting Sarah Marshall," "Role Models," and "Horrible Bosses." Rudd takes the prize for hottest former "Friends" actor at this exact moment.
Then/Now: David Schwimmer
David Schwimmer has found success starring in independent films such as "Duane Hopwood" and "Big Nothing" and was the voice of Melman in "Madagascar." He has also appeared on "30 Rock," and directed the 2008 film "Run Fatboy Run" which received rave reviews. In February 2009, he returned to theater in a Chicago production of Thornton Wilder's three-act play "Our Town as George Gibbs." Then in 2012 he was on the big screen again in "John Carter."
We like Ross's diversity. We mean, Schwimmer's diversity.
Then/Now: Tom Selleck
Tom Selleck played Monica's love interest Richard Burke in Seasons 2, 3 and 6. He joined the cast of the now-canceled NBC drama "Las Vegas" in 2007, and currently stars in the CBS cop-drama "Blue Bloods."
But really, at the end of the day, who cares. He was Magnum - everything else is gravy.
Then/Now: Matt LeBlanc
Matt LeBlanc has disappeared since his spin-off series "Joey" was canceled during its second season. His production company, Fort Hill Productions, co-produced the made-for-TV movie, "The Prince" in 2006. In 2011 he began starring in the series "Episodes."
Then/Now: Giovanni Ribsi
Giovanni Ribsi had a recurring role as Frank Jr., Phoebe's brother. Since "Friends," he has appeared in multiple episodes of "My Name Is Earl," earning a 2007 Emmy nomination, and successful films including "Lost in Translation," "Boiler Room," "The Dead Girl," and has several more films in the works. Frank Jr. turned into a big movie star! Who knew? He recently starred on the cancelled 2013 tv show "Dads."
Then/Now: Lisa Kudrow
Lisa Kudrow has had only minor successes since playing the role of ditzy Phoebe. Lisa starred and served as co-creator, writer, and executive producer in the HBO series "The Comeback." The series earned her an Emmy nomination and was recently brought back for a second season after it was initially canceled. She has also had small roles in several films including "Hotel for Dogs," "Powder Blue," "P.S I Love You" and "Easy A."
She has been producing "Who do you Think You Are?" since 2010.
Then/Now: Jon Favreau
Jon Favreau played Monica's boyfriend Pete Becker. Since then he has directed and/or starred in tons of box office hits including "Elf," "The Break Up," "Something's Gotta Give," "Couple's Retreat," and many more. He was also in all three installations of "Iron Man." He is so money.
Then/Now: Hank Azaria
Hank Azaria made his first appearance on "Friends" in 1994 playing the recurring character David, one of Phoebe's boyfriends. Since then he has continued to work as one of the principal voice actors on "The Simpsons" and has appeared in countless films including "Along Came Polly," "Dodgeball," and "Run, Fatboy Fun," as well as many Broadway productions. Azaria is the definition of a working actor. The guy will be working until he croaks.
Then/Now: Courteney Cox
Jen's BFF Courteney Cox has also found post-"Friends" success. In 2007, she starred in and served as co-executive producer of the FX series "Dirt," which was canceled after the second season. She has been starring on the hit show "Cougar Town" since 2009.
On the personal side, she and actor David Arquette split in 2010 and their divorce became final in May 2013. They were married 14 years and have a daughter, Coco. She is engaged to Snow Patrol band member Johnny McDaid.
Then/Now: Aisha Tyler
Aisha Tyler appeared in several episodes playing Joey's girlfriend, and then Ross's. She followed this up with guest spots on "CSI: Miami" and "Nip/Tuck," as well as balancing recurring roles on both "CSI: Crime Scene Investigation" and "24." She has been a co-host on "The Talk" since 2011 and was recently named the new host of "Whose Line is it Anyway?"
Then/Now: Matthew Perry
After "Friends," Matthew Perry made his directorial debut in an episode of "Scrubs" and also guest-starred in the series. He has appeared in several TV movies including the TNT movie, "The Ron Clark Story," which earned him Golden Globe and Emmy nominations. In 2006-2007, he appeared in the NBC drama "Studio 60 on the Sunset Strip," which bombed big-time. He tried again in 2012-2013 with "Go On," but that was also canceled after just one season.
Kind of a let down, as he was always our favorite, and once dated Julia Roberts.
