Rachel Bilson, taking her dog, Thurmen Murmen, out for a walk in Hollywood. Also out on the jaunt: Bilson’s mother.
Lindsay Lohan, snapping pictures of herself with her BlackBerry from her private booth at West Hollywood’s Villa. There with a group of friends, the actress reviewed every picture before taking the next. Later, Lohan grabbed a real camera and showed off pictures of her sister and mother to a companion in the booth before getting busy on the dance floor as the club filled up.
Adrian Grenier, taking in an after-midnight show by Prince at Hollywood’s Green Door. The singer delivered, playing a two-hour, three-encore set that found stars like Kelis, Christina Milian and the Entourage actor weaving and bobbing to the music. Grenier took up a center table, drinking and laughing with his pals – and, at one point, sharing a tender, chatty moment with Amy Smart.
Paris Hilton, continuing her world travels with musician beau Benji Madden. In London where Good Charlotte is set to perform, the two stopped by the famous Harrods for a little shopping.
Lukas Haas, performing an acoustic set with his brother, Nikolai, at Winston’s in Los Angeles. The actor-turned-singer participated in the club’s special “Eject the Tape” performance series, as the audience cheered him on.
