Jack Black has insisted that Angelina Jolie did not tell him about her pregnancy, and he thought the news was just common knowledge.

The School Of Rock funnyman let it slip at the Cannes Film Festival that his Kung Fu Panda co-star is expecting, even though Angelina had not made the news publicly known.

But Black insists Jolie was relieved the news was made public.

He says: "Later she told me she was relieved because she and Brad (Pitt) didn't want to hold in the secret."

And Black insists Jolie never told him she was expecting: "I think my wife told me. She'd just read it in some rag. Then I thought that was common knowledge."
