fashion week PETATim Gunn, Olivia Munn and Taraji P. Henson have very little in common -- except for their love of animals. All three are spokespeople for PETA, advocating for the rights of animals.

Gunn, Munn and Henson joined forces at Stella McCartney in New York City to kick off an animal cruelty free fashion week and reveal Henson's "I'd Rather Go Naked Than Wear Fur" ad.

"Whenever I get passionate about something, it's all good for me," Henson said of posing nude for the campaign.
