FRIENDS hosted a wide range of famous celebs who made cameos on the show, including Sean Penn, Reese Witherspoon, Bruce Willis and, Jennifer Aniston's ex Brad Pitt.

As fans get ready for the upcoming reunion episode, which is set to premiere on Thursday, we revisit some of the most iconic guest appearances, including celebs you forgot about.

Sean Penn

Sean comes into the show as Phoebe's twin sister's fiancee, Eric.

In an odd twist of fate, Erica leaves Ursula for Phoebe, who then cheats on her with the evil twin.

Reese Witherspoon

Reese plays one of the most recurring characters in the show, Rachel's younger sister, Jill.

Similarly to how Rachel was introduced to the group of friends, Jill comes in as a spoiled girl who was kicked out of their father's credit card and needs to learn the value of money.

Bruce Willis

Bruce comes in as one of Rachel's love interests, Paul, after Ross had begun dating his daughter, Elizabeth.

However, because Elizabeth was just a college student at the time, Paul had an issue with Ross, causing them to have a feud throughout the episodes.

Brad Pitt

One of the most iconic Thanksgiving episodes is the one where Brad Pitt shows up as Ross's old high school best friend.

Similarly to Monica, his character had been heavier during high school and now had lost most of the weight, shocking the group of friends with how attractive he was.

It was later revealed that he and Ross had an "I Hate Rachel" club after she ignored them due to her popularity.

Paul Rudd

Paul has a permanent role in the show for the last season after he plays Mike Hannigan, Phoebe's last love interest.

Despite her reservations and his parents' dislike for her, the two get engaged and tie the knot in a stunning Christmas wedding.

Joey, who was Phoebe's best friend among the crew, officiates the wedding.

Jeff Goldblum

In season nine, Jeff comes in as Joey's fellow actor, but the Friend actor was too star-struck to properly audition for the role.

Sadly, Joey is too nervous to even nail their rehearsals.

Freddy Prince Jr.

Freddy comes in as Ross and Rachel's baby sitter, Sandy, once they have their daughter Emma.

Because of his gender-neutral name, Ross had believed he was a female babysitter, which throws him off.

Winona Ryder

Winona plays a pretty iconic and ground-breaking role in the show: Rachel's first girl-on-girl kiss.

The two had been out and about and after a couple of drinks, Winona's character makes a move and kisses Rachel, before denying it after.

After Rachel kisses her a second time, she confesses her feelings for her, but ultimately, goes home broken-hearted.

Ben Stiller

In season three, episode 22, Ben portrays one of Rachel's many boyfriends after she and Ross break-up the first time around.

He was deemed as "the screamer" because his character had quite the temper and would pick fights with almost everyone.

In the end, of course, Rachel broke up with him after he screamed at Joey and Chandler's pet duck.

Denise Richards

In season seven, episode 19, Denise made an appearance on the show as Monica and Ross' cousin, Nancy.

The blonde bombshell was featured as the hot cousin who had Chandler, who at the time was already engaged to Monica, staring too much.

Her character was so stunning that she even had Ross believing they could forget they were cousins and have a sexual relationship.

Susan Sarandon

Also in season seven, Susan embodies one of Joey's co-stars, Jessica Lockheart, in Days Of Our Lives.

Despite their age difference, the two begin a sexual relationship, much to Rachel and Monica's excitement.

Danny DeVito

In season ten, Danny portrays a stripper that Phoebe had hired for Phoebe's bachelorette party before she marries her love, Mike.

Officer Goodbody, as he was dubbed in the show, comes in dressed as a police officer who simply can't even make it up the stairs to Monica and Chandler's apartment.

Alec Baldwin

Alec made an appearance during an episode in season eight as Parker, "the enthusiast guy."

The two date for just episodes but broke up because he was simply too happy for Phoebe's liking.
