Kate Hudson had Matthew Bellamy by her side as they left a friend's house in LA yesterday. The duo were apparently getting a head start on Cinco de Mayo celebrations, and Kate marked the holiday early by baring her stomach in a cutoff Strokes tee and tiny shorts. Kate is back on the West Coast after a stint in NYC, where she hung out with her boys Matthew, Ryder, and Bingham and promoted The Reluctant Fundamentalist. During press for the movie, Kate opened up about balancing motherhood and work. She'll soon be getting a little extra recognition for her role as a mom since Mother's Day is coming up next weekend. Kate and her mom Goldie Hawn have a "hike, spa day, and tennis date in the desert" planned to mark the occasion, which they shared with us during a recent interview in the Big Apple.
