Gwen Stefani is one hot mama [1]! 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 fishnet stockings and a rockabilly ponytail [2], 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?

Over the weekend, Gwen's country-singer boyfriend hosted the Nickelodeon Kids' Choice Awards [3], and since Gwen wasn't able to attend [4] because she was in Japan, she sent her son, Zuma Rossdale [5], instead. Keep reading to see more of Gwen, and then look back at all her casual outings from 2015 [6] that might as well have been red carpet appearances.
