Out-of-control cougar Drew Barrymore!

Pals warn the troubled thesp to get ff the cougar kick before it bites her in the proverbial arse.

33 year old Drew’s been spotted with no less than three boy toys since her breakup from Justin (Still a Mac) Long.

"It’s a little gross," a Drew pal told The NY Daily News. "She’s getting over Justin and making all these really bad decisions."

First Drew was lip locking costar Landon Pigg, 25, on the set of new flick Whip It.  Then she was photographed with Gossip Girl boy Ed Westwick, 21, at a Kings of Leon concert in New York.  Spies told the tab Drew then went deep dishing with a 24 year old waiter at West Village greasy eatery The Spotted Pig.

Pals told The News that the Westwick canoodle was a prank for the photogs but the others definitely weren’t.

"Ed and Drew saw the cameras and said, ‘Let’s suck face,’ but the other two are a little more serious."

Maybe Drew should just forget about post-Mac tyros and find a nice PC to settle down with.
