Katy Perry Reportedly Caught John Mayer Cheating!

John Mayer's womanizing ways have finally caught up to him.

In a new report, Star claims that Katy Perry kicked the  "Who You Love" crooner to the curb -- possibly because she learned about Lauren McHale, a 24-year-old SoulCycle instructor who had become involved with Mayer.

A source told the magazine that Mayer and McHale met at a bar in L.A. in mid-May and quickly hit it off.

After chatting over drinks, they went back to McHale’s house for a party with a few of her friends.

“They kissed,” divulged a source. “It was very innocent. They didn’t sleep together.”

“They texted for a few weeks before it fizzled out,” the insider added. “They haven’t seen each other since."

According to a close pal, 36-year-old Mayer had reportedly grown distant in recent weeks because he felt pressure to get engaged to Perry – and got fed up with her constantly sporting diamond rings on that finger to create buzz about their relationship status.

“That drove him away,” explained the source. “He wasn’t ready.”
