In the battle for Katy Perry's heart, right now there are rumors of a Robert Pattinson romance as well as a John Mayer reunion in the works. But Perry's pals are rooting for only one of those guys. Which one?

According to OK! Magazine (via FemaleFirst), Perry's friends want her to date Pattinson because they believe he'll be a steady and good influence on Perry's life. One friend explained, "My vote is for Rob. John is a bad boy and sadly Katy prefers that. She always falls for guys with an edge. With that edge comes drama and John is the king of drama."

Unfortunately, Perry's friends think she's going to go back to Mayer for one reason: "John is a physical guy and Katy says it has been the best sex of her life."

Perry recently revealed to Vogue that she's still "madly in love" with Mayer, but did say that their relaysh was kaput. "It's over ... I was madly in love with him. I still am madly in love with him. All I can say about that relationship is that he's got a beautiful mind. Beautiful mind, tortured soul," she said. "I do have to figure out why I am attracted to these broken birds."

Well, we know why she's attracted to this bird -- it sounds like at least part of him ain't broken. Still, we'd love for her to give R-Pattz a shot, because they could mend their broken hearts together!
