DOES hunky Robert Pattinson need to check himself into rehab?

Aussie tabloid NW — who earlier this year claimed Rob’s girlfriend Kristen Stewart was pregnant with his baby — says Rob is drinking vast amounts of booze and needs to get help before it’s too late.

A source claims Rob — who is Canada shooting the third Twilight movie Eclipse, “has been tearing it up in Vancouver and living his celebrity lifestyle to the extreme.”

“He loves the dive bar Loose Moose, where fights break out in the middle of the day and the nights are wild,” the source adds.

“On several occasions, when Rob emerges from the club, his clothes have been stained with puke, and his shirt was once buttoned all weird.”

In March this year, Pattinson, 23, apparently got “beyond wasted” at a party in Los Angeles — but still managed to endear Paris Hilton to his table!

“Paris was on a mission — she kept chasing him around like a little puppy,” a source said at the time.

“He was beyond wasted. He couldn’t keep track of who he was talking to and couldn’t have cared less about her.

“No matter how drunk he was, Rob know better than to hook up with Paris.

“It was hilarious! After Paris managed to get Rob alone in a room, he ran off and she couldn’t find him. Paris kept walking around asking people where he went.”

While Rob might like the occasional tipple, we’re doubtful he has an alcohol problem!
