In case you didn't know, Hollywood's favorite rehabilitated star, Lindsay Lohan, turns 21 today... and that means she is legally allowed to do anything! (Well, pretty much anything.) Our photogs spotted her out and about this weekend at Taverna Tony's in Malibu, shopping at Planet Blue Boutique and, most interestingly, being escorted out of the Chateau Marmont hotel late at night. Hmm, let's hope La Lohan stays clean and sober on her b-day!
