Lindsay Lohan turns 22 today and yesterday she geared up for her birthday as responsibly as she knows how — with another day on the set of Labor Pains [1]. Today she took the day off, treating herself to a shopping spree at Cartier with Samantha. We'll still have to wait and see what happens at her birthday party at Teddy's tonight [2], but we're hoping LL is finally ready to leave her troublesome nights behind for good. She's also got plenty of other things on her mind these days — besides the stories about her illegitimate half sister trying to become a singer herself [3], Lindsay is rumored to be teaming up for a duet with Lily Allen [4] for Lily's new album.
