American swimming great Michael Phelps and his model wife Nicole Johnson's son Boomer has been hogging the spotlight with recent pictures on Instagram. The one-year-old, who has an Instagram account of his own, was pictured soaking up the sun along with family dogs Juno and Legend. That same day, little Boomer took a rest on their big comfy couch at home. "Just lounging around today. #chillinlikeavillain," read the caption on Boomer's Instagram picture.
