Jack Black and his wife, Tanya Haden, are parents of a baby boy, the actor said.

"I'm going to be the best daddy on the planet and I'm going to enter the best daddy competition. And I'm going to win it," Black said in a story posted on the Web site of the magazine Us Weekly.

The couple's first child was born on Saturday, Black told "Access Hollywood" Monday evening at the Mann Grauman's Chinese Theatre premiere for his new movie, "Nacho Libre."

"I've got the babe back at home safe and sound and I'm actually very anxious to get back" to them, Black, 36, told the program.

Neither Us Weekly nor "Access Hollywood" reported the baby's name.

Black has starred in films including "The School of Rock" and "King Kong," and has a band called Tenacious D.

Haden, 35, is a cellist and the daughter of jazz great Charlie Haden.
