Their whirlwind romance seems to have come to an end. According to insiders, Kate Hudson and Lance Armstrong have decided to go their separate ways. Troubles stemmed from their constant bickering and hectic work schedules, insiders tell the New York Post. Kate tried to patch things up at last week's Livestrong Summit, but "they both decided it wasn't feasible," according to a friend. Another insider tells the paper the couple had a huge fight last week and "they didn't talk for like five days."
