Death @ people thinking straight guys like Katy for her music.
Whoever posted that pic of her **** is spot on. She's a VERY attractive girl. But aint no straight guy out there jammin' to California Gurls.
No straight man is watching Katy Perry shoot gummy bears with whip cream coming out of her cupcake bra because he likes the jam. AND if you don't think that whole scenario involves effort from Katy you're also delusional.
She's a smart pop star and knows how to sell. She puts a LOT of effort into what she does. So does Rihanna.
