• He bragged that he would be joined by special guests during a series of concerts at his Hailey, Idaho, bar The Mint – and Bruce Willis wasn't kidding. During the second of his two-night stand, the actor's daughter Rumer Willis emerged from the side of the stage – where she had been dancing – to perform for the crowd. According to a concertgoer, the younger Willis earned thunderous applause as champagne-sipping guests took in the show. Meanwhile, the night before, Willis and his band was joined by Steve Miller.

• Kristin Cavallari, introducing herself to Lionel Richie inside Villa, a West Hollywood club. After shaking the '80s icon's hand, the Laguna Beach star returned to her friends who were dancing to Eminem's song "Lose Yourself."

• It wasn't all business for Lindsay Lohan during her visit in Capri, Italy. Sure, she was there to be honored at the 12th annual Capri Hollywood Film Festival, but the starlet also made a shopping trip to the island's small Prada shop, and enjoyed a dinner at the Relais La Palma.

• Tyson Beckford, hosting the opening of Club Nikki in Miami's South Beach. The model presided over the festivities – and guests enjoyed champagne on the club's plush white couches or outside on a back deck overlooking the beach. Beckford and his entourage hung outside before hitting the VIP stage, a clubgoer reports. Other guests included: Damon and Marlon Wayans and former Project Runway finalist Uli Herzner.
