New York-based actress Michelle Williams and Hollywood actor Jason Segel have broken up after about a year of dating, UsMagazine.com reported Tuesday. A source told the magazine the romance couldn\'t survive the long distance and the couple ended it this month. Segel recently signed up for a ninth and final season of the TV sitcom \"How I Met Your Mother,\" which will keep him in Los Angeles. Williams lives with Matilda, her 7-year-old daughter, in Brooklyn. The little girl\'s father is the late actor Heath Ledger, who died in 2007 of an accidental drug overdose.
