2008's I Kissed a Girl unequivocally launched the pop star's career, and for good reason - at the time, it was quite a scandalous and taboo song for the mainstream crowd. The video itself is very sexy (you can check it out above), but Katy went on to launch a sultry, boundary-pushing career that she's still at the top of. 

On Saturday, she received the National Equality Award at the Human Rights Commission Los Angeles Gala, and gave a short but sweet speech. In it she revealed that yes, the song was inspired by her real-life sexual experiences, and she didn't stop at just a kiss:  

"Truth be told, I did more than that!" she said. "But how was I going to reconcile that with the gospel-singing girl raised in youth groups that were pro conversion camps? What I did know was that I was curious, and even then I knew that sexuality was not as black and white as this dress. But in 2008, when that song came out, I knew that it started a conversation that a lot of the world seemed curious enough to sing along to it."

We have not yet seen Katy date a woman, so I'm not sure if she is indeed bisexual or perhaps more bi-curious. Either way, it's hot, and I'm into it.
