Lohan agreed to spend 90 days in a "locked in" drug rehab facility as part of a plea deal to settle criminal charges against her.
Her six years of legal troubles trace back to two drunken driving arrests in 2007 and include other incidents in which she was behind the wheel, as well as lying to police that she wasn't behind the wheel during one incident in 2012.
As a result of the charges stemming from the accident, her probation in a 2011 theft case was revoked in December. The "Liz & Dick” star still faces up to 245 days in jail for violating her probation.
The actress raced from New York this morning, tweeting around 7 a.m. ET time that she was flying by private jet to Los Angeles.
“Thanks Mr. Pink for the private jet see you all in a few hours in LA @drinkmrpink @sheerazhasan,” she wrote.
Mr. Pink is an energy drink.
Her plane had been scheduled to land at the Van Nuys airport but was instead diverted to Los Angeles International Airport, which is closer to the courtroom.
"A suggestion -- don't drive," Los Angeles Superior Judge James Dabney told Lohan after he handed down her sentence.
"I'm very confident that you won't be seeing Lindsay Lohan in any criminal courts anytime in the future," Mark Heller, Lohan's attorney, said outside the courthouse. "She has fully recognized all of the issues that have to be addressed, and I'm very confident she'll be able to move forward in her life with dignity, pride and respect."
