Days after being cited
for driving under the influence, Lindsay Lohan
has checked into rehab, her rep confirms.
"Lindsay admitted herself to an intensive medical rehabilitation facility on Memorial Day," Lohan's publicist said in a statement Tuesday.
"Because this is a medical matter, it is our hope that the press will appreciate the seriousness of the situation and respect
the privacy of Lindsay as well as the other patients receiving treatment at the facility."
Earlier on Tuesday, a family source told PEOPLE that the recent developments have been hard on Lohan's family, including mom Dina. "She's doing the best she can," says the source.
As for Lindsay, the source says: "We are all praying for her."
This is the second time this year that the 20-year-old star has been in a treatment facility. Her first stay, at the Wonderland Center in West Hollywood, started on Jan. 17
. At the time Lohan issued a statement saying: "I have made a proactive decision to take care of my personal health."
This time, TMZ.com
reports that Lohan has entered Promises treatment center in Malibu. The decision to enter a program comes in the wake of Lohan being cited for DUI after a car accident in Los Angeles. On Saturday morning around 5:30 a.m., Lohan crashed her 2005 Mercedes SL-65 convertible into a curb and shrub on Sunset Boulevard. Lohan, who had left the scene by the time police arrived, was hospitalized for minor injuries. Two passengers were not hurt.
Police said in a press conference Saturday afternoon that they recovered a substance tentatively identified as "a usable amount of cocaine" in connection with the accident. However, authorities refused to specify where the drugs were found.
Rather than keep a low-profile after the accident, on Sunday Lohan hit a private party in a poolside room at Hollywood's Roosevelt Hotel. Early the next morning, photo agency X17 snapped pictures of the Mean Girls
star apparently asleep or passed out in the passenger seat of a friend's car.
One source close to Lohan told PEOPLE over the weekend that friends were hoping she would again seek treatment. "I think she'll have to do a real rehab this time, and not just a Hollywood rehab."
The first time she went to rehab, Lohan stayed at the facility for one month – but left during that time to continue filming
her movie, I Know Who Killed Me,
which is due out July 27.
After ending her stint there, Lohan told Allure
magazine that she first went to the Wonderland center with a friend and found "a quiet room, all white, with parquet, and it was different! I just felt safe," she said. "I thought, 'I'm going to stay here tonight.' And I stayed there. For a month. It was great."
