Actress Cate Blanchett

Actress Cate Blanchett has given birth to her third child, a spokesman said Monday.

Blanchett, 38, delivered son Ignatius Martin Upton on Sunday in Sydney, said Tim McKeough, media relations manager at the Sydney Theatre Company, where Blanchett and her playwright husband are co-artistic directors.

"All are well and very happy," McKeough said.

The newborn weighed 7.94 pounds, he said.

Blanchett and husband Andrew Upton have two other sons: Dashiell, 6, and Roman, 3.

The Academy Award-winning actress next appears with Harrison Ford in the movie "Indiana Jones and the Kingdom of the Crystal Skull," due in theaters in May.
