John Mayer and Bikini-Clad Sheryl Crow Tour Together

John Mayer may still be tapping the backside of Jessica Simpson from time to time, but it appears as though a new contender is trying to get the rocker's attention.

Now single after a long relationship with Lance Armstrong, Sheryl Crow isn't shy about strutting her older - albeit still somewhat sexy - stuff, is she?

Rumor has it that this stunt was actually Crow's retaliation for Mayer interrupting her set by coming out in a bear costume (seriously). But it appears as though the singer is trying out for a part on one of Sara Evans' husband's favorite films.

Try not to come on so strongly, Sheryl. You're making Victoria Beckham look subtle.
