Lindsay Drinks 'Cause Her Parents Stink

We're told Lindsay has been humiliated by her dad Michael going on national TV saying he got shortchanged in his divorce case. He's on a campaign trashing Dina. As for Dina, Lindsay can't believe she's pimping out Ali on a reality show. We're told that is what led Lindsay to hit the bottle Saturday night in NYC.

Ironically, we're also told Lindsay has been taking sobriety seriously, requesting a sober companion on the set of her new film. People around her are telling her not to go to clubs but she's ignoring them -- but it's not because she wants to party. Lohan is really really tight with DJ Samantha Ronson, who works in clubs -- and Lindsay is there for Sam, not the scene.
