Multi-Tasking

Not only can John Mayer sing and play guitar, but he can also talk on two cell phones at the same time!

The soft rocker was spotted leaving the Chateau Marmont in West Hollywood on Monday night.

Mayer held his holiday concert in LA this past weekend, which was quite the star-studded affair. Spotted there: Demi & Ashton, Penelope Cruz and John’s latest gal pal, actress Minka Kelly.
