The former tennis star, 36 – who won a gold medal at the 1992 Olympics and made a winning return to the sport in the early 2000s – was charged Wednesday with stalking and battery in a Valentine's Day clash with Ivan D. Brannan Jr.
The Palm Beach Post reports that the former tennis star was given notice to appear in court April 17.
Capriati allegedly punched Brannan in the chest at a local gym.
In documents, the description for the stalking charge says that the athlete did "willfully, maliciously, and repeatedly follow, harass, or cyberstalk" Brannan between Feb. 16 and Feb. 18.
Neither Capriati nor Brannan, 28, would comment for the story.
The couple split in February 2012, and Brannan told North Palm Beach police that his ex harassed and stalked him after their breakup.
