John Mayer Heckled Over Douchebag Tendencies

John Mayer is a douchebag. It's no surprise that the general populace is beginning to treat him as such - especially ladies fed up with his antics.

A source who recently spent time with the singer tells Us Weekly that he got berated on the street that night for how he's treated ex-girlfriends.

"Girls came up and yelled at him, saying he was a horrible person," says a source of Mayer, whose list of dubious antics is not exactly short.

This is a man who once decided to hold an impromptu press conference with celebrity gossip photographers to discuss his split with Jennifer Aniston.

This is also a man who famously referred to another ex, Jessica Simpson, as "sexual napalm" and likened boning her to a crack cocaine addiction.

Women are not fans. Continues the source, "Girls asked how he can treat women this way. People would tell him exactly what they thought of him."

Now the lame crooner says he is looking for "a new team to manage his image," adds an insider. "He wants to change people's perspective on him."

Here's a free tip: More singing. Fewer musings on masturbating.
