10 BEST Celebrity Cameos In Friends

10. Brad Pitt

Brad Pitt appeared in season 8 episode "The One With The Rumour", and his cameo in the show served more than one entertaining purpose.

At the time, he was in a relationship with Jennifer Aniston, although his character Will was the co-founder of the I-Hate-Rachel-Club, and also started a rumour that Rachel was a hermaphrodite.

It wasn't too long later that their real life relationship ended, making it a little uncomfortable to watch, but still funny nonetheless.

Pitt slots perfectly into the show, convincingly playing Ross' lifelong friend, and he worked brilliantly within the show's dynamic.

He delivered the sort of cameo that made fans wish that he would make another appearance, but his one-shot performance as Will made for a deliciously awkward and hilarious episode.
