Funnyman Jack Black has another reason to smile.

His wife, Tanya Haden, is pregnant with their second child, he said.

"Yes, she's expecting," Black said at a Beverly Hills hotel during a press day for his latest project, "Be Kind Rewind," People magazine reported Saturday on its Web site.

He declined to offer more details.

Black and Haden, a cellist and the daughter of jazz great Charlie Haden, were married in 2006. They have a 1 1/2-year-old son.

Black said he employs a "day-by-day" strategy to parenting.

"I've been told that two children is three times as hard as one child, but then strangely three children is easier than one," he joked.

Black's films credits include "The School of Rock" and "King Kong," and he's a member of the band Tenacious D.
