Callooh! Callay! After a 90-day court-ordered stint in rehab, Lindsay Lohan is back among the (law-abiding) living.

E! reports that La Lohan left the Cliffside Malibu rehab center last night (July 30) at 6:00 p.m. PST, lit up a cigarette, and hopped in a waiting SUV that drove off into the inevitable sunset.

She then reportedly went to a play in nearby Topanga, Calif., and then possibly spent the night at a "private residence." (No word whether that's part of her extended stay at low-level sober housing.)

Another court hearing for her case is scheduled today to see how things are going, but LiLo is not required to attend unless there are questions about the two years of probation she got as part of her March 18 plea deal.

Up next for Lindsay: A guest-hosting stint on 'Chelsea Lately,' and an exclusive interview and docuseries with Oprah.

Good luck, lady. We're pulling for you. And as RuPaul says, "Don't f-- it up."
