Former tennis star Jennifer Capriati has been charged after police said she punched her ex-boyfriend on Valentine's Day while he was working out at a gym.

Palm Beach County court records show Capriati was charged by prosecutors on Wednesday. She has been issued a summons to appear before a judge on April 17 on stalking and battery charges, though she has not been arrested.

North Palm Beach police say Ivan Brannan was working out when the 36-year-old Capriati approached him and yelled at him.

Mr Brannan told police that he tried to get away by walking to the men's changing room, but Capriati blocked his path and punched him in the chest.

Mr Brannan told police he and Capriati broke up in 2012 and that she has harassed and stalked him since then.
