Is Natalie Portman Secretly Married?

Something you'd like to tell us, Nat?

Natalie Portman made a resplendent return to the Academy Awards on Sunday one year after she triumphed with her Best Actress win for her searing performance in "Black Swan."

Back in February 2011, the star, now 30, was pregnant and engaged to her "Black Swan" choreographer Benjamin Millepied.

The handsome Frenchman, 34, was once again Portman's date at the 2012 bash as she presented the Best Actor award to "The Artist" star Jean Dujardin, and the happy parents of son Aleph, 7 months, were more affectionate than ever. (Portman wore a vintage red chiffon silk Christian Dior Couture gown with velvet polka-dot detail.) Both Portman and Millepied -- famously private about their relationship and son -- were wearing unexplained new rings on their wedding fingers.

Compared with pics from the 2011 Oscars, Portman's dazzling engagement ring appeared to be flanked by an additional band. Millepied, meanwhile, wore a simple silver band on his wedding finger. Portman's rep did not reply to a request for comment from Us Weekly.

During her Oscar acceptance speech last year, a tearful, pregnant Portman thanked "my beautiful love" at the podium. "He has now given me my most important role of my life."

The couple, who fell in love while making "Black Swan," announced they were engaged and expecting in late December 2010.
