John Mayer looked a little forlorn driving away from the Chateau Marmont last night after an evening spent with friends. Yes, David Beckham was at Chateau, too...quite the manjoyment-fest. Maybe John was missing his girl Minka, or maybe something happened to his famous OJ Rolex. Oh no! Either way, hopefully, he turns that frown upside down soon. Then again, some of the best music in the world comes from sad songwriters.
