A spokeswoman for the actress said Friday that Blanchett and her husband, Andrew Upton, have adopted a baby girl. Edith Vivian Patricia Upton joins the couple’s three sons, ages 6, 10 and 13.

Publicist Stephanie Gonzalez said no other details will be provided.

Blanchett, 45, can next be seen on the big screen in Disney’s “Cinderella.” She won her second Academy Award last year: best actress for “Blue Jasmine.”
