Megan Fox celebrated her bisexuality in a post for pride, where she wore a rainbow-inspired manicure in the photo she captioned, "Putting the B in #LGBTQIA for over two decades." 

Fox has spoken about her bisexuality in the past, including in 2009, when she told Esquire, "I have no question in my mind about being bisexual."

She stated, "I'm not a lesbian. I just think that all humans are born with the ability to be attracted to both sexes. I mean, I could see myself in a relationship with a girl — Olivia Wilde is so sexy she makes me want to strangle a mountain ox with my bare hands. She's mesmerising. And lately I've been obsessed with JENNA JAMESON, but... oh boy.

I think people are born bisexual and they make subconscious choices based on the pressures of society. 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."
