John Mayer

On-again, off-again musical couple Katy Perry and John Mayer celebrated his 35th birthday by enjoying lunch in New York City. The couple that spends bdays together and chows down together should stay together, right? You never know with this fickle, makin' up and breakin' up couple.

The season premiere of 'Saturday Night Live' kicked off with a bang, featuring musical guests Frank Ocean and John Mayer. The chemistry between the performers is palpable and a lot of fun to watch, and they brought an intensity to the otherwise lighthearted show -- but still didn't take themselves too seriously.

John Mayer may have some legal headaches ahead of him. The singer is now being dragged in a lawsuit over a $100 million Ponzi scheme.

Lots of people do it.  They cut their hair after a break-up.  Is that why John Mayer did it?
