FLORIDA: Cheryl Hines isn’t proving popular with her boyfriend’s kids. The star is dating Bobby Kennedy - son of former U.S. Attorney General Robert F. Kennedy. Bobby’s kids have apparently  even given the blonde actress a new nickname – “Buzz Kill”. “Cheryl might as well be wearing a ‘kick me’ sign on her back,” said an insider, because Bobby’s kids can’t stand her no matter how hard she tries to win them over. Bobby, 59, was in the midst of a bitter divorce from his second wife, Mary, when he and Cheryl began dating. mMary killed herself in May 2012, soon after Bobby and Cheryl took their romance public.–SS
