Fantasia Barrino says she's having a boy, but she refuses to reveal the father's identity.

"I'm at home. I'm on bed rest right now," the American Idol Season 3 winner said on The Wendy Williams Show Tuesday, adding that she's due Dec. 29.

She announced her pregnancy during a concert in August. She has yet to disclose who the baby's father is, and when Williams asked the 27-year-old singer if it was Antwaun Cook, a married man with whom she previously admitted to having an affair, Barrino said: "I'm not gonna talk about that."

Barrino is already a mom to 10-year-old daughter Zion.
