Kate Hudson and Matthew Bellamy went casual for a walk in London yesterday. They're back in England after a jaunt last week to Italy, where Kate premiered The Reluctant Fundamentalist at the Venice Film Festival. Matthew accompanied Kate on the trip and even suited up to attend the premiere by her side. Kate spoke about their family life in the UK while doing press for her Mira Nair-directed drama. Kate wants their son Bingham, who's just 1 year old, to know his British roots. She said, "Bing is getting both sides of where he comes from. It's important for Bing to know he's British . . . even before I met Matthew I've always loved London. I've shot a lot of films there, for a long period of time."
