Hollywood Poison! John Mayer Can’t Find A Date After Being Blackballed By Famous Exes

He may be a hunk with a golden voice, but OK! has learned exclusively John Mayer can’t find a date, after being blackballed by his Hollywood exes!

On the latest episode of the popular podcast Straight Shuter!, host Rob Shuter reveals the “Your Body Is a Wonderland” singer is anything but a wonderful partner.

“John treated Jessica Simpson, Jennifer Aniston, Katy Perry, even Taylor Swift terribly,” a source told Shuter. “In Hollywood, everyone knows to stay away from him.”

As fans know, the disdain Aniston has towards Mayer continue to this day, nearly a decade after the two split up in 2009, after more than a year of dating.

According to Shuter, Jennifer Lawrence and other A-list celebrities want nothing to do with the 40-year-old singer.

“He’s a great musician, but a terrible boyfriend,” sources told Shuter, who used to work for Jessica Simpson when the two singers dated, and confessed without getting into specifics that he didn’t treat her very well.

Among Mayer’s more memorable foot-in-mouth moments: famously calling ex-girlfriend Simpson “sexual napalm;” claiming that African American actress Kerry Washington “would break your heart like a white girl;” and proclaiming, “All I want to do now is f**k the girls I’ve already f**ked, because I can’t fathom explaining myself to somebody who can’t believe I’d be interested in them.”

Mayer himself even recently admitted his bad reputation is hurting him in the bedroom, telling Watch What Happens Live host Andy Cohen if you are someone who cares about your image, “dating John Mayer at this point is conceptually a no-no.”

“I don't have the greatest track record when it comes to celebrity relationships,” he said on the show. “It's amazing to watch your friends humor me on a friend level but also keep a fair distance from me.
