The party is finally over for Lindsay Lohan.

The 20-year-old starlet checked herself into a rehab center after an all-night drinking binge following the Golden Globes on Monday night.

Lohan didn’t attend the awards show, but went to the parties later and wound up at Prince’s after-after party at the Beverly Wilshire. Witnesses say she caroused until 6 a.m. Tuesday and was later found passed out in a hotel hallway.

As Page Six first reported in November, Lohan flirted with sobriety by attending some AA meetings. A friend of Lohan told us then, “She has decided to turn her life around – this time for good. She is out of control.” But celebrating New Year’s in Miami, Lohan was seen drinking from water bottles refilled with vodka.

Lohan’s publicist, Leslie Sloane Zelnik, released a statement yesterday from the actress: “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.”

Us Weekly reported on its Web site that Lohan arrived at the Wonderland Center in L.A.’s Laurel Canyon yesterday at 2:30 p.m. wearing black tights and a leather jacket. She was spotted getting out of an SUV and entering the facility carrying a Balenciaga bag and Jamba Juice.

According to the facility’s Web site, the Wonderland Center is a “residential treatment and detoxification facility providing services for alcohol, substance abuse and relapse-prevention programs.”

“We provide first-class food service and accommodations. Secure and gated on a private estate, the Center has two swimming pools and three acres of sitting and walking areas,” the Web site says.

Lohan, who made her movie debut at the tender age of 11 in “The Parent Trap,” has since become one of Hollywood’s hottest young stars.

She recently had surgery to remove her appendix.

A 2005 article in Vanity Fair quoted her as saying she had an eating disorder, but she later denied making the remark.
