Lindsay Lohan was in trouble again Thursday for turning up late to community service, a day after a judge revoked her probation for previous similar failures, dpa reported.
She arrived late for her court-ordered community service at the Los Angeles morgue and was sent away.
Lohan, 25, later tweeted an apology, claiming that a media scramble and confusion over the entrance she needed to go through accounted for her tardiness.
"I'm sorry for the confusion that I may of caused to those at the Coroner's office. Won't happen again, now I know where to go! Thank you for your help," she tweeted.
According to celebrity website TMZ.com the coroner who was meant to supervise her rejected the excuse, telling reporters that Lohan had been to the morgue before and knew exactly where to go.
In a court hearing Wednesday, Judge Stephanie Sauter revoked Lohan's probation on a shoplifting conviction for her repeated failure to perform her community service as proscribed.
A sentencing hearing was set for November 2, and bail at 100,000 dollars.
While Lohan could face a one-and-a-half-year prison sentence, overcrowding in the California prison system means she will likely serve a far shorter term.
Sautner had earlier ordered Lohan to complete 360 hours of work at a Los Angeles women's centre as part of her probation for shoplifting a necklace in February.
In Wednesday's hearing, the judge also said Lohan had "blown off" her order and had been reassigned to a Red Cross program without court approval.
Sautner said that Lohan had missed nine out of ten appointments and had performed only two hours of service.
"Her probation would have been done last year if she had done what she was supposed to do," the judge said. "There has been violation after violation. Probation is a gift. It's not a right."
