Jack Black confirms Jolie twins

Angelina Jolie and Jack Black will promote their new movie at the Cannes Film Festival today, after the actor let slip his co-star was expecting twins.

The pair are in Cannes for the animated film Kung Fu Panda, for which they provide the voices.

As the festival got under way, Black dropped the hint during a side-by-side interview with Jolie for a television show.

He joked to Jolie that she and husband Brad Pitt will "have as many as (the) 'Brady Bunch' when you have these."

"It's confirmed?" asked NBC interviewer Natalie Morales.

"Yeah, yeah, we've confirmed that already," Jolie said. "Well, Jack's just confirmed it actually."

"Is that true?", Black said jokingly.

"Yeah, you did," Jolie replied.

"Sorry," Black said.

Excerpts of the interview were being broadcast last night on Access Hollywood, with the full interview airing on today's NBC's Today.

Twins make the fifth and sixth children for Jolie and Brad Pitt.
