Borat’s Kid Has an A-List Birthday

By: Janie Marcus / October 20, 2008

Very nice!

Fearlessly fierce funnyman Sacha Baron Cohen and Isla Fisher‘s daughter Olive turned a year old yesterday, and an illustrious assemblage of guests turned out to celebrate.

Superbad‘s Jonah Hill, Courteney Cox, David Arquette, Ben Stiller, newlyweds Ellen Degeneres and Portia de Rossi, and Jennifer Aniston convened at Cohen’s Hollywood Hills home to party down.

Also on hand: Dustin Hoffman, because every kid’s birthday party needs a clown.

Also there to attend the festivities but not pictured: Aniston’s recently rekindled flame, John Mayer. Which makes perfect sense, since he and the host have so much in common.
