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, 33, 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 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.

Mayer famously called ex Simpson, 30, "sexual napalm" in a shocking Playboy mag interview. "Kim's a class act," Stanger says. "So I'd never put her with him."

What kind of guy is right for Kardashian, then? "I'd like to see Kim go to the A-list," Stanger mused. "So I'd like to get an A-list actor who likes a brunette hottie...She needs someone who is strong who will allow her to build her empire. She needs someone serious."
