Ray-Ban Wayfarers in Brentwood, Calif. The actress made several stops, including a trip to a candy store.
Owen Wilson, going incognito in a baseball cap as he hung out near the deejay booth at West Hollywood lounge Winston's. The actor, who recently returned from vacationing in
Maui, chatted with a female clubgoer. Also making the scene:
Orlando Bloom, hanging out with four friends at a corner table.

Elisha Cuthbert shared girl talk and the heiress danced to her own single "Stars Are Blind" with pal
Brandon Davis. Later in the night, Hilton and her posse moved from the front of the club to a corner table behind a tree, where former
O.C. star
Adam Brody joined them.

Lindsay Lohan, changing up her look several times at New York City club Stereo as friend
DJ AM spun records. The actress showed up wearing a black leather jacket over a low-cut white shirt, but she came with a backup outfit: a Ramones T-shirt, which she later slipped over her white shirt sans jacket. But ten minutes later, the actress made yet
another change, taking off her white tee and putting
back on the Ramones shirt and jacket. Lohan – with an entourage that included her mom
Dina – grooved to the music and eventually made her exit with two Red Bulls in hand.
