Asked about Angelina’s growing bump, comedian Black, 38, joked to her: “You’ll have as many as the Brady Bunch when you have these.”

“It’s confirmed?” asked NBC interviewer Natalie Morales.

“Yeah, we already confirmed that. Well, Jack’s just confirmed it actually,” replied Angelina, looking shocked at her co-star. “Is that true?” Black laughed. “Yeah, you did it,” Angelina replied, shrugging her shoulders. 

“Sorry,” Black replied, holding his hand to his mouth.

Angelina then blushed furiously as Black continued to talk about her expanding family with Pitt. 

They have a biological daughter Shiloh, two, and have adopted boys Maddox, six, Pax, four, and daughter Zahara, three. Maddox is Cambodian, Pax Vietnamese and Zahara Ethiopian. 

Then yesterday, in another press con-ference, Angelina finally admitted: “Yes, they are twins.” 

Asked about the place of birth, she said: “We are certainly thinking of France.” She said French was a second language that all her children were starting to speak – “so being here is very good for them at this time,” she added.

Her late mother Marcheline Bertrand was French and Angelina is said to be keen for her children to have dual nationality.

Angelina said she knew the sex of her babies but that she and Pitt wanted to “keep that private”.

She and Pitt have been preparing for Cannes, and the birth, in style.

The unmarried pair have moved into Microsoft billionaire Paul Allen’s Cote d’Azur villa, along with ten staff.
