Happy birthday, PETA!

On Saturday (Dec. 12), the animal rights organization will be celebrating its 40th anniversary with a virtual party hosted by Alan Cumming. The event will honor its Humanitarian Award recipents including Jermaine Dupri (presented by Mariah Carey), Lily Tomlin (presented by Dolly Parton), Kansas City Chiefs star Tyrann Mathieu (presented by Patrick Mahomes), and Iggy Pop (presented by Chrissie Hynde).

Paul McCartney, Gillian Anderson, Alec Baldwin, Anjelica Huston, James Cromwell, Belinda Carlisle, Casey Affleck, Pamela Anderson, Bill Maher and Edie Falco will also make appearances, while Jesse & Joy will deliver a special performance before receiving their own Humanitarian Award.

“Forty years ago, car companies used pigs as crash-test dummies and people thought a vegan was someone from Las Vegas,” said PETA President Ingrid Newkirk in a press statement. “Today, animals in laboratories are being replaced with super computers and organs-on-chips, fur is dead, elephants are out of the circus, and the Tiger King is in jail.”
