Oscar-winning actress Angelina Jolie said in a television interview on Wednesday that she is expecting twins with actor Brad Pitt, the Hollywood couple's fifth and sixth children.

Jolie, being interviewed at the Cannes film festival alongside comic actor Jack Black for the syndicated entertainment program Access Hollywood, acknowledged that she was having twins after Black made reference to them.

"Yeah, yeah, we've confirmed that already," Jolie, 32, said, according to a transcript provided by the show. "Well, Jack's just confirmed it actually."

Excerpts of the interview, conducted by a reporter for NBC's Today show to promote the animated film Kung Fu Panda, featuring characters voiced by Jolie and Black, was set to air on Access Hollywood on Wednesday night.

The full interview will air on Thursday on Today.

Jolie and Pitt, 44, together have adopted three-year-old daughter Zahara, six-year-old son Maddox and four-year-old son Pax.

They also have a biological daughter, 22-month-old Shiloh.

Jolie won an Academy Award as best supporting actress for her role in the 1999 film Girl, Interrupted.
