They're moving in together!
They celebrated Christmas together!
We never thought this would last, but hey, everyone can be wrong sometimes, and Katy Perry and John Mayer kinda had the odds against them. Katy and John have been dating for a long time now, and now they're getting tired of living at two separate places - so they've decided to move in together! "'He always insisted he needed his own place to make music but clearly that's changed. Now he mostly hangs out at Katy's place in LA.'', an insider reveals. They've both said they're very serious with each other, and we wish them all the best!
