Actress Megan Fox, [top picture] best known from TV show Hope And Faith and the film Transformers, has announced that she’s bisexual. Although, bizarrely, she said she’d never sleep with another bi woman.

“I think people are born bisexual and they make subconscious choices based on the pressures of society,” Fox told Esquire magazine. “I have no question in my mind about being bisexual.

“But I’m also a hypocrite. I would never date a girl who was bisexual, because that means they also sleep with men, and men are so dirty that I’d never want to sleep with a girl who had slept with a man.”

Bizarrely, Fox is engaged to a man – Beverly Hills 90210’s Brian Austin Green.

“I mean, I could see myself in a relationship with a girl,” said Fox. She said that Olivia Wilde [bottom picture], from The OC and House, is at the top of her list. ”[She’s] so sexy she makes me want to strangle a mountain ox with my bare hands.”
