Kate Hudson and Matt Bellamy went out in London last night for a late one at the restaurant 45 Park Lane, where they grabbed a bite with Kate Moss and Topshop boss Philip Green. The two Kates, who also partied together last week at Stella McCartney's 40th birthday bash, seem to be good pals, and Moss's own rock-star significant other, Jamie Hince, joined in on the meal. Despite the evening out on the town, Kate and Matt were up and at 'em this morning, taking their young son, Bingham, along to breakfast at a North London cafe. Kate and Matt have been in his home country of England for the last month, so they can introduce Bingham to his Bellamy relatives. Their European location also allowed Matt and his band Muse to wrap up a Summer tour as well as freeing him and Kate to vacation in the South of France with Bingham and his big brother, Ryder.
