Jack Black and wife Tanya Haden are adding another baby to their family, the actor said Saturday.

"Yes, she's expecting," Black told reporters at the Be Kind Rewind press day at the Four Seasons Hotel in Beverly Hills. He declined to name a due date.

The couple, who eloped in March 2006, are already parents to a 1½-year-old boy.

So far, Black says he's taken on parenting with a "day-by-day" strategy. "I've been told that two children is three times as hard as one child," he joked, "but then strangely three children is easier than one."
