“I’ve told my boyfriend [John Mayer] that if Scarlett Johansson wanted to go out with me, I’d ditch him immediately,” Katy told Entrevue magazine (via MTV). “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.”

Katy added, “When I was 15, I fell in love with a female friend. I thought she was beautiful and wanted to be like her. She had such a huge impact on my life, but I never told her how I felt.”
