Gwen Stefani carried her platform heels leaving a nail salon with freshly painted toes in LA on Saturday. The philanthropic star recently made a $1 million donation to the victims of Japan's natural disaster and now she's holding an online auction to raise additional funds. Starting April 11, Gwen's fans have the chance to bid on limited-edition Harajuku Lovers t-shirts, vintage L.A.M.B. items straight from her closet, and an exclusive meet and greet with the star at a private Harajuku-themed tea party in LA! While she waits for the bids to start rolling in Gwen's been keeping busy with her boys. The foursome have been spotted taking family trips to museums, snapping cute photos on the beach, and snacking on yummy after-dinner treats.
