Jen Aniston boy-toy singer John Mayer is being auctioned off on E-bay for only $25,000!

But it’s not what it sounds like – John is set to headline a four-day cruise aboard his party ship Mayercraft Carrier 2, and the winning bidder will get to hit the high seas with the famed musician.

The opening bid is set at $25,000 and proceeds will go to the charity "Musicians on Call," a nonprofit organization that helps patients in healthcare facilities.
John and his pals will set sail from San Pedro, Calif. on March 27, and will cruise the Sea of Cortez while he personally entertains and hangs out with them during the cruise.   

In addition to a private audience with Mayer, the four winners will receive a personally signed guitar, and round-trip airfare to Los Angeles and two nights at the Santa Monica luxury hotel Casa del Mar.

Other music stars auctioning off private audiences are Tony Bennett and Celine Dion.

Jen better get in her bid in quick!
