Rumor has it that Kate Hudson celebrated a strange Father's Day event this year. She went out for brunch in Brooklyn, N.Y.,and was accompanied by her ex-husband, Chris Robinson, and their son Ryder. Also joining the Father's day celebration was her new boyfriend Lance Armstrong and his own children Luke,8,and 6-year-old twins Isabelle and Grace. Kate and her ex-husband split up in 2006 after six years of marriage. Lance Armstrong was recently on the view and was asked by the four female hosts if he was dating Kate Hudson and he declined to answer. Neither Kate or Lance have spoken out about their romance to date. So I have to ask on this special father's day celebration who is dating whom?
