A Day In The Life Of John Mayer

John Mayer had quite a busy day yesterday!

The musician went to the gym at 11am, and after he cleaned up, he headed to Siren Studios around 2pm to meet up with Jennifer Aniston. Jen was at the studio for a photo shoot, and we're told it involved dogs, so we're thinking it has something to do with Jen's upcoming flick, "Marley & Me"!

John stayed for three hours, and even though he'd probably rather be doing other things, it's good to see that he's spending quality time with Jen, instead of just booty calling her!
