• When she's not concentrating on charitable efforts, a stylish Gwen Stefani makes time for her husband. The singer grabbed dinner with her equally sporty hubby Gavin Rossdale in Los Angeles.

Rachel Bilson, in Dubai for the 4th International Film Festival, making an appointment for an in-room spa treatment from Natura Bisse. Meanwhile, her Jumpers costar Hayden Christensen "swagged it up" at a gift lounge at the Hotel Al Qasr. And the actor loaded up on one big ticket item: a Kenyan safari.

• She's in Paris for business – to cut the ribbon at the new Nespresso boutique on the Champs-Elysees – but that didn't stop Sharon Stone from doing some music shopping at the Virgin Megastore beforehand.

Jon Stewart, announcing to diners at the Spotted Pig in New York just how much he loved his banana-themed dessert. Calling the treat "crazy good," the Daily Show host and his dinner companions pretended to argue over the bill before taking off from the New York hot spot.

Kate Beckinsale, shopping at the Lisa Kline boutique in Los Angeles with her husband Len Wiseman. The actress scooped up a great Juicy Shift dress before leaving.

Ugly Betty star Becki Newton, taking the (gasp) subway in New York. The funny star, who looked hip and "very downtown," according to an onlooker, walked through Times Square station holding her coffee.
