Kate Winslet picked up her daughter, Mia, and son, Joe, from school in NYC yesterday. The actress has apparently split from Louis Dowler, the British model she began dating after her March breakup from Joe's dad, director Sam Mendes. Kate and Louis were serious enough to take their romance public and travel the globe during their months together, but the actress reportedly initiated the breakup in order to stay focused on her kids. She's been spending lots of time with Joe and Mia this Fall, taking them trick-or-treating and to and from school. Kate also has plenty of other new beginnings to look forward to in 2011, with her miniseries Mildred Pierce airing in the Spring and a starring role in Roman Polanski's upcoming project.
