US Weekly reports that Lindsay entered the Wonderland Centre in Los Angeles at 2.30pm yesterday, arriving in a sports utility vehicle and clutching a juice.

Zelnick confirmed in December that the Mean Girls actress was attending Alcoholics Anonymous meetings.

Lindsay told People magazine then that she had been going to the meetings for a year.

"I haven’t had a drink in seven days. Or anything," she said to People. "I’m not even legal to, so why would I? I don’t drink when I go to clubs. I drink with my friends at home, but there’s no need to. I feel better not drinking. It’s more fun. I have Red Bull."

Last July, Li-Lo was treated for several hours at a Los Angeles area hospital for overheating and dehydration on the set of Georgia Rule.

Lindsay out hours after appendix op - Jan 9 2007
Lindsay Lohan is hardcore. The actress has just been released from hospital after having her appendix removed and celebrated by partying with friends in Hollywood.

But don’t worry, the Alcoholics Anonymous visitor was only spotted with water, whilst she ate dinner at restaurant Pace and then headed over to night club Winston’s.

She was there until half past two in the morning, before scuttling off into the night. The star had been discharged from the Century City Medical Plaza just hours beforehand.

And snarky observers were quick to note the presence of her full red lips, which looked especially plump.

Now that she’s back on the street, Linds had better be thinking about getting back to work. Her last two movies were commercial flops, but she seems keen to stay on the indie tip.

Her latest - Chapter 27, which tells the story of John Lennon assassin Mark David Chapman, is due to screen at the Sundance Film Festival next week.

Lindsay has appendix op - Jan 5 2007
Actress Lindsay Lohan is having surgery to remove her appendix, her publicist said.

In an email last night, Leslie Sloane Zelnik said the 20-year-old actress was "having her appendix removed. She is resting comfortably".

Celebrity website TMZ.com reported Zelnik as saying Lindsay was not feeling well on Wednesday and went to a doctor, who performed several tests and determined she was suffering from appendicitis.

Doctors asked her to return to the hospital yesterday to remove her appendix as a precaution, TMZ said.

Lindsay, whose screen credits include Bobby, A Prairie Home Companion and Freaky Friday, was treated for several hours at a Los Angeles-area hospital last July for overheating and dehydration on the set of Georgia Rule.

She was treated at hospitals twice in January 2006 - in London for a cut on her leg and in the Miami area for an asthma attack. In 2005, she was admitted to hospital suffering from exhaustion and lost a noticeable amount of weight.
