Since the end of "Friends" (and Brad Pitt), Jennifer Aniston has mostly strayed from the spotlight (except for a few shots of her and John Mayer). But the fanaticism over her haircut continues. We managed to snag photos of her latest hairstyles, including a shot of her on the set of "Marley & Me." Check out her looks, from stick-straight (thanks in part to a Sedu flatiron) to soft and wavy.
