Mary Kate Trollsen Lurves Her Fur!

Aww. She dressed up as an Ewok!

On Thursday, Mary-Kate Olsen gave PETA and other animal rights activists across the world another one-fingered salute.

She hit the Belvedere IX party in NY in some sort of animal fur.

What’s the animal you’re wearing, MK Troll?

Any guesses?

We bet she had a big steak dinner later that night to top things off!
