Kate Moss was solo yesterday morning to look at a home for sale in North London, then she headed over to visit with a friend in Notting Hill. The supermodel, who's the star of a new video for Balmain, is gearing up to celebrate her 37th birthday on Sunday. She's set the bar high for her famous parties, after hosting four events in 2008, having a medieval-themed bash in 2009 and getting diamonds from Jamie in 2010. She's got a head start on the good times recently by having a lunch date with Jamie and a New Year's extravaganza in Thailand, so we'll see what she has in store for this weekend.
