Lindsay Lohan arrives Nov. 29 at the 2006 GQ Magazine Man of the Year dinner in West Hollywood.
Lindsay Lohan has checked herself into rehab, according to a statement issued through her publicist, Leslie Sloane Zelnik.
"I have made a proactive decision to take care of my personal health. I appreciate your well wishes and ask that you please respect my privacy at this time."
Just last month, the 20-year-old actress revealed that she had been attending Alcoholics Anonymous meetings for a year.
"It's a place to go and feel safe," Zelnik said at the time. "No one judges her, and it's going to be a slow process. But, to me, the fact that she's seeing that there's something not right makes her smarter than the next person."
In December, she was seen partying with exotic dancers in New York City. The "Mean Girls" star has embarked on pole-dancing lessons to prepare for a role in the upcoming film "I Know Who Killed Me."
In July, the studio producing Lohan's upcoming picture, "Georgia Rule," accused her of "all night partying" - which caused her to miss work and cost the studio "hundreds of thousands of dollars" in damages. Lohan blamed "heat exhaustion."
In a July 26 letter to Lohan, the CEO of Morgan Creek Productions, James G. Robinson, said Lohan was "discourteous, irresponsible and unprofessional" and acting "like a spoiled child."
Despite her reputation as a party girl, Lohan had long denied that her social life had gotten out of hand. In a November appearance on Oprah Winfrey, she said, "Is it a crime to go dancing with your friends?"
It hasn't been an easy January for Lohan. Earlier this month, she was hospitalized for an appendectomy.
