The kids are back together & love is in the air (again). Katy Perry & beau John Mayer are apparently not only back together (officially), but also recording MUSIC together.
All I know is this: it can't be any worse than Avril Lavigne & Chad Kroeger, right? Listen to "Who You Love" below!! [PopCrush]
The song appears on Mayer’s new album ‘Paradise Valley,’ out Aug. 20.
