Gavin and Zuma Rossdale shared a frozen yogurt treat yesterday in LA. The boys are back home after spending their weekend with Gwen and Kingston hitting the slopes on a family ski trip to Mammoth. Gavin's currently holding down the fort while Gwen's off on her latest fashion adventure. She's scheduled to debut her new L.A.M.B. collection during NYC's Fashion Week later this month — make sure to enter Fashionologie's contest by midnight PST today to win a trip for you and a guest to the Big Apple for a special show! Kingston even made a cameo with Gwen on the runway at the end of her presentation in September, so maybe the guys will head east to spend a very special and stylish Valentine's Day as a family.
