Natalie Portman 'Secretly' Married?

Black Swan star Natalie Portman and her fiance Benjamin Millepied have sparked rumours that they may already have married after appearing to be wearing wedding bands at this year's Oscar ceremony.

The 30-year-old actress was spotted wearing a second ring alongside her engagement ring while presenting the Best Actor award to The Artist's Jean Dujardin, while ballet choreographer Millepied also appeared to be wearing a band on his wedding finger.

The couple, who generally keep their private life out of the public eye, first met on the set of Black Swan, with Portman giving birth to their first son, Aleph, in June last year.

The pair have yet to make any official comment.
