Gwen Stefani is one hot mama! On Monday, the singer drew all eyes when she popped up at designer Keita Maruyama's fashion show in Tokyo. Gwen, who stunned in a black romper complete with a floral jacket and fishnet stockings, seemed to be aware of how hot she looked; at one point, she was spotted snapping a couple selfies in the audience - perhaps she was sending them to Blake Shelton?
