Ricky Martin isn't the only one coming out this week: "True Blood" star Anna Paquin just revealed she's bisexual.

Paquin -- who's engaged to her male co-star Stephen Moyer -- broke the news in a new PSA for the Give a Damn Campaign, reportedly saying: "I'm bisexual, and I give a damn."

Paquin and Moyer -- who got engaged last summer -- have yet to announce a wedding date.
