Clay Aiken is set to become a father for the first time.

The singer, who has repeatedly refused to address rumours that he is gay, is having the baby with his best friend, music producer Jaymes Foster.

A spokesman for 50-year-old Foster's music mogul brother David Foster has confirmed she is pregnant via artificial insemination, and due to give birth to the 29-year-old American Idol star's child in August.

Bill Vigars tells People: "The story is true... Clay is the father. She was artificially inseminated by Clay. She's due in August... She looks great, glowing and very happy.

"She and Clay have been good friends ever since American Idol, when they worked together."

Aiken is reportedly thrilled with the news and plans to be an ever present father to the child, even though he has no plans to wed divorcee Foster.
