Former tennis star Jennifer Capriati was charged with battery and stalking after allegedly attacking her ex-boyfriend at a gym on Valentine's Day. Talk about getting into the swing of things - police say Capriati threw a punch at her ex while he was working out at a North Palm Beach gym. Ivan Brannan told police he tried to get away from Capriati, but she blocked his path and then uncorked a punch to his chest. Brannan says the two broke up in 2012 and that she has stalked and harassed him ever since.
