Lots of stars flocked to the Hollywood Palladium in Los Angeles to celebrate PETA’s 35th anniversary party.
Stars who attended the bash - like Pamela Anderson, Ireland Baldwin and Jason Biggs - sat down to a gourmet meal and the chance to participate in a stellar silent auction.
Also, excitingly, Paul McCartney performed with his band to the crowd of partying celebrities.
In terms of the outfits, things took a demure turn with famous glamour model Courtney Stodden having a Marilyn Monroe moment in orange and Clueless actress Alicia Silverstone wearing a floorlength black gown.
