Kate Hudson and Matthew Bellamy hopped on their bicycles today for a ride around London. They ran a few errands before heading home via Primrose Hill. Riding on two wheels is apparently a hobby for the couple — Kate and Matt were seen biking in Malibu with Goldie Hawn and Kurt Russell back in LA. The proud new parents are in Matthew's home country to introduce their 5-week-old son, Bingham Hawn Bellamy, to his British relatives. Kate and Matthew arrived in London a few days ago after taking off from their California home base with big brother Ryder. It has been reported that Kate and Matthew want to split their time between the US and England, so that the children can get to know both sides of their family. To that end, Kate and Matthew spent $6.5 million earlier in the year buying property in North London.
