Katy Perry has never been shy about admitting that she had a crush on a female friend at 15. Hello! That's what allegedly inspired her first smash hit 'I Kissed a Girl.' However, Perry never revealed to her friend that she was crushin'. Actually, it was more than crushin'. It was her first love.

Perry said, "When I was 15, I fell in love with a female friend. I thought she was beautiful and wanted to be like her."

While Perry was super into her friend, she never made a move and never smooched her. She continued, "She had such a huge impact on my life, but I never told her how I felt." She never got that taste of her Cherry ChapStick.

It's been said that pillow-lipped actress Scarlett Johansson also inspired 'I Kissed a Girl.' Apparently, several years later, Perry still harbors her girl crush on Scar Jo.

"I’ve told my boyfriend that if Scarlett Johansson wanted to go out with me, I’d ditch him immediately," she said, referring to her current BF, John Mayer. "Female beauty can be incredibly powerful. Actually, I’m obsessed with beautiful women and their elegance. I like the paradox of appearing innocent and sexy all at once."

Innocent and sexy? Yeah, that sounds like our gal Katy Perry.
