Evan Rachel Wood
The True Blood cutie opened up to Esquire about her same-sex dating habits, saying, "I'm more kind of like the guy when it comes to girls...I'm the dominant one."
Tom Hardy
The Inception hunk seemed to have opened up about his Brokeback past recently, saying, "There's plenty of stuff in a relationship with another man, especially gay men, that I need in my life." Though, the actor is now claiming his quotes were taken out of context.
Anna Paquin
The Oscar winner may be engaged to her True Blood costar Stephen Moyer, but she had the courage to come out as a same-sex-lovin' celeb earlier this year. "I'm bisexual," she announced in a PSA for Cyndi Lauper's gay rights project, Give a Damn.
Ewan McGregor
The actor has admitted he likes swapping spit with dudes. "I like kissing boys on screen," he told Out magazine. "As a straight guy, it's quite an interesting proposition. Anything on a film set that takes you by surprise like that, that gets your blood up, is good."
Lindsay Lohan
Samantha Ronson. Enough said.
Lady Gaga
Was anyone really that surprised when the "Poker Face" songstress told Barbara Walters in January, "I've certainly had sexual relationships with women, yeah."
Angelina Jolie
Before she was globe-trotting humanitarian mom of six, Ang was a free-lovin' wild child. Not only did she have a relationship with her Foxfire costar Jenny Shimizu back in 1996, but she reportedly has said, "If I fell in love with a woman tomorrow, would I feel that it's OK to want to kiss and touch her? If I fell in love with her? Absolutely! Yes!"
Ke$ha
She may be singing about a boy in her latest hit, "Your Love Is My Drug," but Ke$ha apparently doesn't limit herself, saying recently, "I like people. I wouldn't say I'm gay or straight. I don't like labeling things anyway. I just like people."
Dave Navarro
The rocker made out with Tommy Lee on a red carpet to promote their reality show, Rock Star: Supernova. Navarro isn't bi, but once said, "I've never been aroused by a man, but I've been in situations where I could potentially be aroused."
We're not sure what that means, but we'll take it.
Madonna
The queen of reinvention has never shied away from girl-on-girl play time. The big question remains: Is it real or just another part of her marketing genius?
Kourtney Kardashian
Kourtney Kardashian caused some waves down in Miami during the first season of her and Khloé's reality show when she kissed a girl...and liked it. "That was a fun time," she told us last summer.
