Scarlett's Lips Inspired Katy's Singing?

Apparently Scarlett Johansson's lips inspired Katy Perry's song "I Kissed a Girl". Not that Scarlett really seems to care. People says:

When told that her lips inspired Katy Perry to pen her hit "I Kissed A Girl," Johansson, who recently married Ryan Reynolds, tells December's Allure, "That's flattering, but my lips are kind of taken."

In fact, until Perry's melody was pointed out to her, "I had no idea [about the song]," says Johansson, 24. "I should get a cut!"

I don't really know why, but I find her response really annoying. The fact that Perry's song was actually inspired by something to do with women pleases me immensely, but Scarlett's response is just a bit irritating for some reason. It seems to have one of those (fine, be attracted, but remember, I'm not gay and you can never have me" sort of intonations. Or maybe I'm just crabby. Yeah, I think I'm just crabby. I still think she's hot, though.
