Kim has been warned to stay away from John Mayer

Millionaire Matchmaker's Patti Stanger doesn't want Kim Kardashian to follow in the footsteps of Jennifer Aniston or Jessica Simpson: she urges Kardashian to stay away from fellow serial dater John Mayer.
The New York Post reported Tuesday that Kardashian, who turns 30 Thursday, and Mayer, 32, recently hit the town in NYC. Although they brought pals along, the duo wanted "to see if they would hit it off," a source told the Post.
Even before the Post's report, Stanger was dead set against the match. "No! He's a douchebag," she told UsMagazine.com last month of the outspoken, quirky rocker.
"She'd chew him up and spit him out and chew him up again," Stanger adds of Kardashian, who's been single since splitting from Miles Austin last month.
