Halle Berry, holding hands with Gabriel Aubry during a shoe shopping trip to New York's Bergdorf Goodman. The actress kept her sunglasses on as she browsed – then left with a pair of black suede Giuseppe Zanotti boots.
Also on a shopping spree: Isla Fisher, who spent almost $900 at L.A.'s Trina Turk boutique. Among her purchases, the actress scooped up a pair of black jegging pants ($212) and a cardigan ($228).
Leighton Meester, mingling with guests like Barbara Walters and Billy Crudup at the New York Public Library's 2009 Young Lions gala. After the dinner, the Gossip Girl star, who attended with dapper beau Sebastian Stan, headed downstairs to a dance party with young library donors and music spun by DJ Cassidy.
Kara DioGuardi, lounging by the adults-only Hibiscus Pool while vacationing at the Grand Wailea in Maui with husband Mike McCuddy. The duo also dined at the resort's floating Humu Humu resort, where the American Idol judge ordered the grilled Ahi tuna rare.
