Lindsay Lohan "In Distress" and "Staying Inside"

Source close to L.L. thinks the actress finally realizes her situation

Lindsay Lohan may still be "freaking out" at the fact she has to spend 90 days in the slammer, but friends say she's "doing all right."

Now she's spent not one but two nights in a row at home—thanks to Kim Kardashian lending a hand or, rather, Chinese food. Why? A source close to Lohan says it's because no matter how pissed off she may be at her sentencing, Lindsay does not want to get her ass in more trouble:

"Obviously Lindsay doesn't think the outcome was entirely fair, but at this point, the most important thing for her to do is make sure during the next two weeks she doesn't give the judge reason to extend her sentence," a source close to Lohan tells E!

"She's in distress right now. She realizes there is still a possibility of having more jail time added on. She understands the best thing to do right now is stay inside," adds our LiLo insider.

Still, the Lohan pal stressed that while L.L. may know what she should do, doesn't mean she'll actually do it.

"We all hope she doesn't go out during the next few weeks."

Well, so far so good for the actress.

Linds had two parties planned the last couple of nights and skipped out on both (and we're sure it doesn't hurt that there are dozens of paps stalking outside, waiting for that partying shot).

Tuesday L.L. was scheduled to throw another birthday party at Drais at the W in Hollywood, and last night she was supposed to have another bash at hot spot Las Palmas.

Since Judge Revel's decision, Linds has decided to stay home, which we think is pretty damn smart of her.

Maybe the blonde really is ready to turn things around—or do you think the good behavior is just a phase? Post your thoughts below.
