Lindsay Lohan has checked into rehab. "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," said the 20-year-old actress in a statement issued Wednesday through her publicist, Leslie Sloane Zelnick.

Us Weekly reports that Lohan entered the posh Wonderland Center in Los Angeles at 2:30 p.m. Wednesday, arriving in a sports utility vehicle and clutching a Jamba Juice.

Zelnick confirmed to The Associated Press in December that Lohan was attending Alcoholics Anonymous meetings.
