Now that Katy Perry and John Mayer are back on again, the 'Fireworks' songstress is laying down some ground rules for the 'Paper Doll' singer-songwriter. If he wants to date Perry again, he's got to follow some dang guidelines!

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?

Get excited! John Mayer announced that his new album 'Paradise Valley' will hit stores on Aug. 13!
