Lindsay Lohan had a good reason to be late for a holiday party at Hollywood club Shag in on Monday. "I just left an AA meeting," she told PEOPLE.
"I've been going to AA, for a year by the way," she added. Why didn't she say so until recently
? "Well it's no one's business. That's why it's anonymous!"
At the Angeleno
magazine party for Nefarious Fine Jewelry's spring 2007 collection, Lohan scored more than $40,000 worth of bling, including a "Spider Web" diamond necklace (pictured, left), a diamond ring and a pair of diamond-encrusted aviator sunglasses.
"I haven't had a drink in seven days. Or anything. I'm not even legal to, so why would I?" Lohan, 20, told PEOPLE. "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."
But, she added, "I didn't feel bad before. I never felt bad. I just wanted to, like, find a balance. I was out too much. I was too caught up. I mean, I'm 20 years old. I was off from work, I was getting ready to start a film, and I was like going out just to get it out of my system. I was going out too much and I knew that, and I have more to live for than that."
Lohan said she hopes to shift the focus from her partying to her career. "I was like, I don't want to be written about at these clubs with these people. I work, I act, I have a living. That's what I do every day. I work every single day."
Asked if she had advice for those seeking recovery from substance abuse, Lohan said, "I think, don't do it for someone else. Do it for you, 'cause if you do it for someone else you're going to relapse. It's not going to be a change. You have to really do something if you want to do it and ... if it doesn't work, you're not meant to."
