Lindsay Lohan: Out of Control and Unwilling to Change?

Things are looking worse by the day for troubled star Lindsay Lohan, according to friends who say she is out of control and resistant to getting her act together.

Less than 24 hours before she clocked Tiffany Mitchell at a nightclub and got arrested, Lohan was "dancing like crazy" and "causing a scene" at another NYC club.

When she thought she lost her phone, says an onlooker, Lohan flipped out, and "she even demanded that a girl at a nearby table empty her pockets."

The following night, Lohan was drunk, according to reports, when she got into it with Tiffany Mitchell. Lohan denies punching anyone, but is due in court January 7.

Punch or no punch, Lindsay continues to struggle with alcohol, says a friend.

TMZ cited a source last week claiming she downs two liters of vodka A DAY. That may be a slight stretch, but few at this point doubt she's got a problem.

One she's either blind to our unwilling to do anything about, her pals lament.

"She will fool people into thinking she's changed this time, but at some point in the night, she always snaps and it's always the same story," says one confidant.

After the nightclub incident, Lohan's assistant Gavin Doyle grew concerned.

He Tweeted to her: "@lindsaylohan after bailing you out last night I HOPE and PRAY you get the help you so desperately need. We are ALL rooting for you. xxx."

Lohan is "out of control," adds a second source, noting that Lindsay refuses to go to rehab. "Her friends don't know what to do. She won't ever change."

After her recent slew of criminal charges - for lying to police following her June car crash - she's due back in a Los Angeles courtroom on December 12.

Because Lohan is still on probation, those charges, combined with the possible assault, could land her in jail if Judge Stephanie Sautner deems it necessary.

A conviction isn't necessary to trigger a probation violation.

The last time the starlet appeared before Sautner, the judge warned Lohan that she could face 245 days in jail if she slipped up again. Think this qualifies?

Despite her apparent downward spiral, some friends insist she'll pull through.

Another source close to the 26-year-old starlet denies that she has a problem and says that it's the "near constant criticism" that's taking a toll on her.

"If everything you did was criticized, you'd lash out too," says the pal.

"But she'll be fine, she's tough. She'll probably outlive everyone."

At this rate, we wouldn't exactly put money on that on InTrade.
