• Lauren Conrad, sharing a friendly outing with former boyfriend Stephen Colletti at The Grove in Los Angeles. The Hills star and her pal went to the movies to see box-office champ Iron Man.

• Nick Lachey and Vanessa Minnillo, chatting with Ne-Yo backstage after his set at Los Angeles's Staples Center. The R&B star was opening for Alicia Keys – and talked with the couple until it was time for the headliner to perform. Before Keys took the stage, Lachey and Minnillo ran back to their seats in the arena. Also hanging backstage: Pussycat Dolls member Nicole Scherzinger and Dakota Fanning. Meanwhile, Britney Spears was also spotted relaxing at the show.

• Christina Aguilera, sipping on a water bottle while out with a girlfriend at West Hollywood's Villa. The singer and her pal actually kept the focus on fashion at the club – with Aguilera's pal chatting about a new pair of jeans, standing up to model them and then try on the singer's scarf.

• Alicia Silverstone, enjoying some girl time with three pals at Spago in Los Angeles. The foursome scored a coveted corner table in the garden where they started the evening with cosmos. They went on to share salads while the non-vegans at the table munched on the famed chopped tuna cones, an off-the-menu favorite.

• Sharon Stone, arriving fashionably late at the sensual Crazy Horse Paris topless dance show inside Las Vegas's MGM Grand. Despite missing the first 30 minutes of the show, the actress (and her two companions) didn't stop smiling – all the while sipping wine. After the show, Stone ventured backstage to compliment the dancers.
