Jack Black has a secret

Jack Black and musician wife Tanya Haden welcomed a baby boy over the weekend.

Black announced the arrival during Monday's Hollywood premiere of his new comedy Nacho Libre, telling Access Hollywood, "Secretly, between you and me, it's already happened. I've got the babe back at home safe and sound, and I'm actually very anxious to get back to my lovin's." Awwww

Black left the premiere shortly after the lights went down and the screening began.
