John Mayer Ready to Cruise Again in His 'Mankini'

Must be something in the salt air.

How else do you explain John Mayer's eagerness to strip down to the barest of Borat-like essentials once he hits the high seas.

"I'm getting my bikini wax for the Mayercraft Carrier," says Mayer, 31, offering a little TMI on Twitter as he prepares to host a cruise leaving Friday from L.A. to Cabo San Lucas, Mexico, for four nights of partying. Last year, the crooner made a splash when he wore a green "mankini" similar to the one worn by Sacha Baron Cohen's alter ego.

Asked when he'll don the thong, Mayer tweeted, "I'm already wearing it."
