Kate Hudson left her newborn son Bingham Hawn Bellamy inside yesterday in order to visit Malibu Beach with her son Ryder. She's been out and about since the birth of her second child last weekend, including a Friday lunch date with both Ryder and Matthew. Kate also went along for a ride with Matthew in the afternoon. They visited a local Starbucks, but Kate stayed in the car while he ran inside to order their drinks. Matthew went the extra mile to explain the origin of Bingham last week, writing on Twitter that the moniker was his mom's maiden name and Kate's stepdad Kurt Russell's father's name.
