"Thanks Mr. Pink for the private jet see you all in a few hours in LA," she tweeted early Monday.
After entering the courtroom, Lohan sat for more than two hours as her New York-based attorney, Mark Jay Heller, and prosecutors ironed out a plea deal.
After a pair of arrests for driving under the influence in 2007, Lohan has resolved her numerous legal issues without going to trial.
Instead she has faced judges who have sentenced her to rehab and counseling, which even her current attorney acknowledges have not completely helped the troubled actress.
Lohan entered Monday's hearing with a lawyer whose competence has been questioned by a judge. At one point during the proceedings, she told an incessant Heller not to "say anything else." Lohan and Heller were joined by Long Beach-based attorney Anthony J. Falangetti.
Lohan's longtime advocate, Shawn Holley, left the case earlier this year after keeping the actress out of jail for significant periods of time on probation violations and the allegation in 2011 that she took a $2,500 necklace without permission from an upscale jeweler.
After Lohan left the courthouse, her father, Michael Lohan, who brought his own legal team to the proceedings, confronted Heller and Falangetti.
Michael Lohan told reporters that Heller was being investigated for witness tampering in the case and was not being paid by his daughter. Instead, Lohan said the attorney took the case to gain media attention. Heller did not respond to the claim by Lohan at the courthouse. A call to his New York office was not immediately returned.
"Go home," Michael Lohan called out to him. "You have done enough damage. Leave my daughter alone and stay out of the press. You're a parasite."
Lohan, who's had a strained relationship with his daughter over the years, was restrained by his attorney and separated from Heller and Falangetti by a sheriff's deputy.
