Just because someone's in a heterosexual relationship now doesn't mean that they're straight — just ask celebrities like Megan Fox and Amber Rose, who identify as bisexual. While their high-profile marriages have been with guys, both ladies have dated females before.
"It was a weird moment in my life when I didn’t know how to like explain to myself I wasn’t gay, but I wasn’t straight and I just wasn’t like some freak—that you know was just having threesomes all day," Amber Rose has said. "For me, if I was in a relationship with a woman then I was just with her and vice versa."
"When I had my first girlfriend—me and my mom are best friends— I just told her and my mom was like, 'Whatever makes you happy girl. Whatever you like, that’s your business, I don’t care.' It was really easy for me."
The model's story is very similar to other stars' — some of whom you may not have even realized were bi. For instance, Fergie, who's married to Josh Duhamel, has been very honest about her sexuality, even admitting that not being with women has been an adjustment.
"Just because I enjoy women doesn't mean I'm allowed to have affairs in my relationship," Fergie has said. "I learned through talking with my therapist that it is still cheating even if it's with girls, so there is a rule there."
