Has Natalie Portman secretly married her beau Benjamin Millepied?

The couple, who have a son together, are known for keeping their private life just that -private – but their appearance at the Oscars on February 26th has sparked questions.

While most onlookers were distracted by Portman’s stunning red polka-dot dress, diamond and platinum necklace and earrings, some noticed a new ring on her finger.

The Black Swan actress wore a sparkling diamond ring that was given to her by Millepied on the occasion of their engagement in December 2010 on her ring finger.

However, she teamed this band with a new simpler plain silver ring, posing questions about whether or not she has secretly tied the knot.

Her Black Swan choreographer partner also wore a silver band on his ring finger, again suggesting they may have wed in secret.

At last year’s Oscars, Portman was heavily pregnant but still looked a vision in purple and took home the Best Actress nod.

In 2011, she appeared in No Strings Attached, Thor and Your Highness but has since taken a break to spend time with her baby Aleph.
