Kate Hudson, in Ipanema sandals, and Matthew Bellamy took their son, Bingham, for a walk in London today. They were out in Matthew's native England all weekend and bumped into pal Gwyneth Paltrow and her family at Starbucks on Saturday. Kate and Matthew are getting back to their daily routine following a visit to Venice last week. They were there to promote Kate's The Reluctant Fundamentalist at the Venice Film Festival and showed plenty of sweet PDA on the red carpet. There's more star power to come at the annual event, but check out all the pictures of the Venice Film Festival so far to get caught up on what's already gone down.
