Gavin Rossdale

Gwen Stefani and Gavin Rossdale were inseparable as they posed for pictures on the red carpet last night at the Heart Foundation Gala. The organization raises money to help research and fight heart disease, and the charitable evening included a performance by Michael Bublé, with Ryan Seacrest handling MC duties. Gavin and Gwen stepped out in support of the cause alongside stars including Chelsea Handler. Gavin took advantage of a 10-day break from playing with Bush to spend the evening with his wife. The band will make several stops in Canada, along with the Midwest and Northwest, before wrapping up their latest tour late next month. In the Fall, it will likely be Gwen's turn to hit the road. No Doubt's reunion album will hit shelves on Sept. 25, the band announced last week, and the foursome are expected to tour widely in support of the new CD.

Today's amfAR Cinema Against AIDS Gala in Antibes drew a glamorous crowd of stars.

Supermodels Doutzen Kroes, Bar Refaeli, and Naomi Campbell joined designers like Karl Lagerfeld and amfAR chair Kenneth Cole at the fundraiser. This evening's swanky fête was one of several that have taken place during the annual cinema celebration. Earlier this week, a Chopard soirée drew many of the same famous faces, including Bar and Jude. Since the festival first kicked off on May 11, the stars have been keeping busy on the gala circuit, relaxing on the water on board mega yachts owned by the likes of Steven Spielberg and Microsoft's Paul Allen, and walking the red carpets at movie premieres like Brad Pitt's The Tree of Life, which debuted on Monday.

Sean Penn shares the screen with Brad and Jessica, and he joined them for today's event as well. Sean's girlfriend, Scarlett Johansson, didn't walk the press line, however. Brad's big evening caps off an exciting week for the Jolie-Pitts. Angelina made the rounds last week to chat up and debut her Kung Fu Panda 2, also making the exciting announcement that her directorial debut will be called In the Land of Blood and Honey and will hit theaters on Dec. 23.
