The 34-year-old former international tennis star was reportedly rushed to the hospital early Sunday from her 19th floor luxury condo in Riviera Beach, Florida, just north of West Palm Beach.
Her father claims that an accidental overdose of prescription medication was to blame.
Her former boyfriend Dale DaBone told TMZ that Capriati got horribly depressed when Grand Slam events were being played, and that she was also upset about his recent return to working in porn.
DaBone had worked in 443 films, the entertainment website reported, and recently signed on with Vivid Entertainment to star in Batman XXX: A Porn Parody.
Meanwhile on CBS's The Early Show today, Justin Gimelstob, a former tennis star and a friend of Capriati's, said he heard from Jennifer's mother, who told him she is doing well physically and is resting.
