Anna Faris (Season 10)
Anna appeared toward the end of the show as the biological mother of Monica and Chandler’s adopted twins.
Danny DeVito (Season 10)
All credit goes to Danny DeVito for his incredible appearance as Phoebe’s surprise stripper at her bridal shower. His memorable crying scene and dance routine made for very enjoyable viewing.
Dakota Fanning (Season 10)
Child actress Dakota was already famous in her own right for starring in Cat in the Hat and Uptown Girls when she made her appearance on the sitcom. She appeared in the final season and befriended Joey as the child who lived in the house Monica and Chandler were viewing.
Paul Rudd (Seasons 9 & 10)
Who can forget Paul Rudd’s ongoing contribution to the show as Phoebe’s pianist boyfriend, and eventual husband, Mike Hannigan. Their love story was really one for the ages.
Christina Applegate (Season 9 & 10)
Christina appeared as the sister of Rachel Green in several episodes, with her snooty attitude making her a memorable character. In fact, her performance was so good, the cameo won her an Emmy for Outstanding Guest Actress in a Comedy in 2003.
Dermot Mulroney (Season 9)
Already loved for his role in My Best Friend’s Wedding, Dermot played Rachel’s coworker turned love interest for three episodes. In an interview, he reveals people would call out to him by his character’s name, Gavin, when they saw him in the street.
Hank Azaria (Seasons 1, 7 & 9)
Phoebe’s scientist boyfriend who leaves her to work in Minsk was certainly a recurring favourite. His character continued to pop up throughout the series, often wreaking havoc on Phoebes’ heart.
Aisha Taylor (Season 9)
Originally Joey’s palaeontologist girlfriend, Aisha eventually found a more compatible match in Ross (not before breaking a few hearts, though).
Alec Baldwin (Season 8)
Alec Baldwin made a memorable appearance as Phoebe’s irritatingly enthusiastic boyfriend. He appeared for two episodes before everyone found his overly joyful personality unbearable and Phoebe decided to end things.
Brad Pitt (Season 8)
Arguably the best celebrity appearance of them all, Brad Pitt nailed the role of Ross and Rachel’s former classmate and founder of the ‘I Hate Rachel Green’ club. Funnily enough, him and Aniston were married in real life at the time of filming.
Kristin Davis (Season 7)
Sex and the City was at the height of its popularity when Kristin made a guest-appearance as Joey’s love interest. Rachel and Phoebe become obsessed with making their relationship last, but unfortunately it didn’t continue for longer than one episode.
Winona Ryder (Season 7)
Winona appeared as a former sorority sister of Rachel who becomes embroiled in a heated debate about whether or not they once shared a kiss. Ultimately, she confesses her undying love for Rachel at the end, but the feelings are sadly not reciprocated.
Susan Sarandon (Season 7)
A dramatically memorable performance came from Susan Sarandon in her role as soap star Jessica Lockhart. Trying to imagine her brain in Joey's body was wildly unbelievable, but extremely amusing.
Bruce Willis (Season 6)
The iconic Bruce Willis appeared on the show for a few episodes as Rachel’s boyfriend, Paul. He also happened to be the father of Ross’ 20-year-old girlfriend which was uncomfortable to say the least.
Reese Witherspoon (Season 6)
Reese absolutely nailed the role of Rachel’s spoiled little sister Jill. She ended up going on a date with Ross in one of the episodes but as we all imagined, it didn’t end well.
Elle Macpherson (Season 6)
Playing the role of Joey’s roommate and eventual girlfriend, Elle’s character made waves for taking a dislike toward the group.
Cole Sprouse (Seasons 6, 7 & 8)
Cole was an adorable addition to the series, playing Ross and Carol’s son. He later revealed he developed a big crush on Jennifer Aniston while filming (and who can blame him)?
Richard Branson (Season 4)
He only appears for a minute but the Richard Branson cameo is a great one. Making a dig at his billionaire status, he’s seen trying to sell cheap merchandise to Joey and Chandler.
Hugh Laurie (Season 4)
The hilarious scene between Hugh Laurie and Jennifer Aniston plays out while she’s travelling over to London to surprise him at his wedding. After growing increasingly infuriated with her, Hugh eventually tells her he believes they were actually ‘on a break’, to the amusement of everyone.
Sarah Ferguson (Season 4)
A trip to London wouldn’t be complete without a cameo from Fergie herself. She even has time to grab a quick selfie with Joey in his ridiculously large Union Jack hat.
Billy Crystal and Robin Williams (Season 3)
Billy and Robin actually made their cameo by chance as they happened to be filming on a nearby set while an episode of Friends was taking place. They stopped by Central Perk for a quick cup of coffee and played out an entirely impromptu scene. Unsurprisingly, hilarity ensued.
Ben Stiller (Season 3)
Ben Stiller has one of the funniest cameos throughout the show, playing Rachel’s boyfriend with extreme anger issues. For some reason, nobody is privy to his outbursts except Ross, but it all comes crashing down eventually.
Julia Roberts (Season 2)
She was one of Hollywood’s biggest rising stars at the time, and Julia Roberts did not disappoint with her cameo. Playing the role of Susie Moss, she comes back to seek revenge on Chandler for a humiliating incident that occured while they were at school together.
Brooke Shields (Season 2)
This well-known actress appears as a Dr. Drake Ramoray (Joey) superfan. She has a hard time understanding that his character on the show isn’t who he actually is in real life, bless her.
