Nana Kadjo Hayes is the fourth son for the former voice of "South Park's" Chef and his first child with his current wife whom he married in May 2005, People magazine reported Wednesday.
The baby was born April 10, weighing in at 8 pounds, 5 ounces, Hayes' rep, Rob Moore, said.
Hayes, 63, quit Comedy Central's "South Park" at the start of last season. The Scientologist cited the cartoon's disrespect for religion, but creators Trey Parker and Matt Stone accused him of sensitivity only when it came to his own beliefs.
Hayes lives in Memphis but the couple's announcement did not say where their son was born.
