Actress Natalie Portman is on cloud nine after announcing that she is engaged and pregnant. The 29-year-old Israeli-American star is expecting her first child with fiance,ballet choreographer Benjamin Millepied,in Spring 2011. "I have always kept my private life private but I will say that I am indescribably happy and feel very grateful to have this experience," the Daily Mail quoted her as telling in a statement to EW.com. The couple met in late 2009 while filming ballet drama ''The Black Swan'',which Portman has received critical acclaim and a slew of award nominations for. French-born Millepied,32,a classically trained ballet dancer who studied at the School of American Ballet as a teenager,was hired by filmmakers to choreograph Portman's dances.
