The stars of "The House Bunny" attended a special CosmoGIRL screening of their new film at The Hearst Tower in New York City on Tuesday night, with each actress showcasing a different 'do.

Emma Stone was vibrant in red, Rumer Willis went for a more dark and mysterious look, while Anna Faris opted for bold blonde bangs and Katharine McPhee wore her hair in a romantic updo.

I'm partial to Emma's classic side-part and rich color, but whose hair do you think deserves the Most Beautiful Bunny title?
