After a harrowing couple of days, Fantasia Barrino is on the mend – and out of the hospital.

The American Idol season 3 champ was hospitalized in Charlotte, N.C., Monday for an overdose of aspirin and a sleep aid, but she was released from the hospital late Wednesday, says her manager Brian Dickens.

"She has been lifted up by the outpouring of love and support from her fans," Dickens said. "She is more committed than ever to her daughter and her work because they are her heart, her soul and inspiration."

The medical scare came just after Barrino, 26, was named in a court filing alleging that she was having an affair with a married man. The singer denied she was responsible for breaking up the marriage of Paula and Cook. However, on Tuesday admitted having dated Cook "off and on for 11 months."

Barrino says she believed Cook and his wife were separated, and is now "heartbroken and is sorry for any pain she may have caused."
