Troubled actress Lindsay Lohan has a court date this morning that will determine whether she goes to jail or continues on house arrest in her luxury $2.25 million 3,000-square-foot townhouse in Venice, CA.

At issue are a couple of alcohol tests that came up positive last week. Lindsay will go before the same judge who threatened her with jail time if she violated her probation again… or was that the judge before this one? It’s so hard keeping up with all the judges, the rehabs, the ankle monitors and the second chances that this girl gets.

But even though Lindsay is a chronic substance abuser for whom drug rehab has failed in the past — her dad, Michael Lohan, still believes she needs drug rehab rather than prison time. Like typical enablers, Lohan blames Lindsay’s friends for all her problems:

“There’s a chubby English girl named Nikki who is always around her and when she is, I get a sick feeling and there is always a problem,” Lohan told PopEater’s Rob Shuter.

Last week Lindsay threw a party on her roof for a small group of friends. She was drinking out of a red cup, but a bottle of beer and wine glasses can clearly be seen in the photos (below).

When interviewed for Life & Style magazine, Lindsay said, “When my friends come over, they’re not drinking. Alcohol is not in my house, so it’s not part of my life.”

“I’m so worried about my daughter,” Michael Lohan told Radar Online. “I’m very, very concerned about the people around Lindsay and the pressure being put upon her. If it turns out that the test was positive, then I have strong concerns because if a person can’t stay straight in the house where can she stay straight?”

Update: Lindsay Lohan does not have to go to jail. A judge today ordered Lohan to stop partying while on house arrest. According to People.com, the judge chided Lohan for making “a party atmosphere” out of her home confinement. She was ordered to limit the number of visitors she has at one time in her home. The judge didn’t revoke Lohan’s home confinement or toss her in jail because her court ordered alcohol testing ended in February.
