Fitness, Fan Flirting for John Mayer

Just because he's got a new love interest in cocktail waitress Scheana Marie doesn't mean John Mayer can't keep his options open.

The singer and serial dater scored in Santa Monica, Ca. yesterday when, during a shirtless workout, a female fan driving by asked him for a kiss. Granting her wish, Mayer leaned into her window and plated one on her lips.

Mayer did an afternoon of exercise with his trainer, and even called for his fans to join him.

"Just got to the Santa Monica steps...somehow picked up 4 paparazzi. You might as well all come join me. Bring workout gear," he Twittered.

Mayer is in the process of recording his forthcoming record Battle Studies.
