Notorious ladies’ man John Mayer has reportedly kissed a boy - and he liked it!

The doe-eyed crooner allegedly locked lips with another man while partying at a popular gay club in Palm Springs, California.

Mayer, who has dated Hollywood beauties Jennifer Aniston and Jessica Simpson, sent the crowds wild as The Black Eyed Peas hit ‘I Gotta Feeling’ belted out in the club.

He was reportedly the centre of attention as he downed bottles of beer and toasted his fellow revellers.

But according to Radaronline.com, jaws dropped when a male admirer approached the singer and planted a big kiss on his lips.

Crowds erupted into cheers and Mayer looked to be enjoying it.

It’s not the first time John has smooched with a man - he has previously confessed to ‘making out’ with openly gay showbiz blogger Perez Hilton.

“You’re damn right I made out with him,” he said at the time.

“I was thinking about going gay!”
