Before they were Hollywood's most wanted, our favorite celebs played hilarious roles on '90s sitcoms. The following revelations will definitely have you thinking, "they were on THAT show?!"
From 'Die Hard' to comedy, Bruce totally cracked us up on 'Friends,' playing the father of a student that Ross dates in season six of the show.
Before the R&B crooner and Oscar winner made it big, he played the outrageous Wanda on 'In Living Color'. Funnies aside, the image of Jamie in drag cannot be unseen...
We all remember Pamela from her blonde bombshell days on 'Baywatch,' but did you know she played Tim Taylor's (sexy) tool assistant first?
Plenty of A-Listers have guest starred in 'Friends' before, but none as iconic as Brad Pitt. The irony in the role he played, as president of the "I Hate Rachel Club" made it even better!
Usher is the last celeb we'd expect to have guest starred in a sitcom, but he did! This smooth lady killer played the fitting role of "The Love Doctor," and we bet he knows plenty about lovin'.
Before he was one of Hollywood's sexiest men, George played Booker Brooks, Roseanne's supervisor. Ever the prankster, he even left a picture of his family jewels on set for the ladies to admire!
Oh the nostalgia! How can we ever forget about Leo's days as Luke Bower, the cute homeless boy taken in by the Seavers on 'Growing Pains'?
