'American Idol' winner Fantasia Barrino was hospitalized Monday night after overdosing on aspirin and a sleep aid following an "overwhelming" day of media backlash for a relationship she's having with a married man, the singer's manager has confirmed.

"She was dehydrated and exhausted at the time," the rep, Brian Dickens, said in a statement to TMZ. "Fantasia is stable now. She will be released from the hospital soon. Fantasia is a fighter and a survivor. This is not the hardest thing Fantasia has endured."

But as her rep attempts to downplay the overdose, a police report obtained by RadarOnline.com classifies the incident as an "801 - suicide" and calls Barrino's injuries "serious."

Barrino was admitted to Mercy South Hospital in Pineville at around 9 p.m. It followed a day of damaging reports linking her as the other woman in a child custody lawsuit against her married boyfriend, Antwuan Cook. The complaint, filed by Paula Cook, claims an affair started in August 2009 and that the two "have at times recorded their illicit sexual activity."
