Lindsay Lohan is out of rehab -- and back in the Twitterverse.

On Thursday afternoon, the star, 24, wrote her first Twitter entry in 36 days.

"Clearly.. Paparazzi shouldn't be allowed to take pictures or video while someone's driving or at a stop light. 4every1's sake," Lohan wrote, using the hash-tag "trafficpolice"

After being sprung from UCLA Medical Center on Tuesday, Lohan was photographed for the first time in a Beverly Hills parking garage -- holding an energy drink, ROCKSTAR, in her left hand. She skipped the L.A. premiere of her flick Machete, where cast and crew wished her well.

"God bless her," actor Don Johnson told UsMagazine.com. "I care about her as a person."

Lohan spent 13 days in jail and 23 days in rehab as punishment for violating her probation related to a 2007 DUI. On Wednesday, L.A. Superior Court Judge Elden Fox prescribed strict terms of supervised probation for the star.

Until November 1, Lohan is barred from leaving California and must attend multiple psychotheraphy, behavioral therapy, and 12-step meetings weekly; she must also submit to random drug and alcohol testing at least twice a week. The penalty for a positive drug or alcohol test: 30 days in jail.
