Cheer up, Johnny!

John Mayer grabbed a bite at Craig's in Beverly Hills last night, and the musician looked a little down in the dumps as he exited the eatery. Maybe he saw online how much fun his ex-girlfriend Katy Perry was having at Coachella and got slightly jealous?

The "Clarity" crooner doesn't have much going on these days, so he might want to re-think dumping his pop princess lady love. His life is so boring these days, he even had time to go to his ten year high school reunion recently.

We wonder if Jessica Simpson, Jennifer Aniston, and Katy Perry die of embarrassment every time they think of falling for this idiot!
