Dad thinks Lindsay Lohan is drinking again

DENVER — Lindsay Lohan’s dad, Michael, should be celebrating his pre-engagement bliss, but instead he’s worrying about his oldest daughter, Lindsay.

“I’ve been up and down the road (in discussions) with my ex-wife (Dina) and it’s to the point now that I’m going to confront Samantha and Jenny Muro (Lindsay’s production assistant) myself,” Michael says of why he is speaking out. 

What has stirred Lohan’s ire? He feels Lindsay is drinking again and her partner, Samantha Ronson, is to blame.

“Samantha drinks and passes the drinks under the table to Lindsay, and behind the scenes it gets worse and worse,” says Lohan. “Sam is using my daughter. My daughter isn’t working because she’s always with Sam. Even my ex-wife knows it. She just isn’t doing anything about it.”

Scoop on Hathaway in DenverLohan hasn’t yet decided how he’ll proceed with handling the situation, but he has begun taking responsibility in his own life.

A rep for Lindsay says, “This is totally a lie and untrue.”

He says he’s been in contact with Kristi Kaufman, who made the claim that Michael fathered her daughter some 13 years ago. “Kristi Kaufman has been called and we have agreed to go through a mutual lab (for a paternity test) over the next 30 days,” says Lohan.

He also chimed in on another scandal, that of John Edwards. “The only advice I can give anyone (in his situation) is be upfront, be honest and we have to try our best never to make the same mistakes again.”

John Mayer, no imagination when it comes to gifts
When you date John Mayer, you don’t just get a boyfriend, you also get a Rolex. Us Weekly reports that the rocker has gifted several ex-girlfriends, the most recent being Jen Aniston, with a Rolex during the course of their romance.

That doesn’t mean Mayer forms great attachments to his exes, however. The mag reports that he’s already moved on from Aniston, and was spotted at NYC’s Goldbar on Aug. 21 with a “very young, supercute blonde.” Then three days later at the Izakaya restaurant at the Borgata, another witness saw Mayer “cozied up” with a brunette over dinner.
