Christina Aguilera Boards the Bi Bus? 

Those comparisons to Lady Gaga plaguing Christina Aguilera were further fueled by her latest single, "Not Myself Tonight," in which she sings, "I'm kissing all the boys and the girls."

But the singer says there's some truth to that line. Ever though she's married to a man, she's definitely into ladies.

Aguilera told Out magazine, "I don't get to kiss all the girls and the boys. but my husband knows that I get into girls. I think it's fun to be open and play. The line is real to me. My husband and I check in with each other, but I definitely love women. I think they're more attractive to the naked eye," she says before adding, "I don't think I could ever really be with a woman because that's a lot of ... what do you call it? Guys have testosterone, girls have ... "

Estrogen?

"Yeah, there's a lot of estrogen and I'm a lot to deal with when it's that time of the month, so I can't imagine it times two. And you know, I love dick. To be honest, that I cannot live without."
