Olivia Munn Goes Nude for PETA, Men Everywhere Stop Wearing Fur (PHOTO)

You might know Olivia Munn as the actress from "Perfect Couples" or "I Don't Know How She Does It." Or, you might know her as the actress who fought off some pretty nasty comments from the always-classy Brett Ratner, right after he got fired from producing the Oscars.

But Munn is also known for her animal rights involvement. She has joined "Glee" star Lea Michele and others in working to ban horse-drawn carriages in New York City, due to the stress it puts on the horses, and she has worked with PETA a few times in the past.

Her latest effort is a new set of posters for PETA with the aim of banning fur, and... well, she's really putting it all out there.

Munn is the latest in a string of stars to do a nude poster (covered, of course) for PETA in protest of fur in fashion. Munn's photo contributed to a billboard in Los Angeles, but the full poster couldn't be shown there (Munn is, after all, naked in it).

The full poster has Munn posed with a bunny next to her, with the caption "Who needs fur to feel beautiful? I'd rather go naked than wear fur."

Check out the two full posters below:
