Telling accessories: Natalie Portman and fiancé appeared to be wearing wedding bands at the Oscars last night
They are known for keeping their relationship out of the public eye.
But Natalie Portman and fiancé Benjamin Millepied may have revealed a big secret to a very large audience when they were spotting sporting some telling accessories to last night's Oscars.
The couple, who announced their engagement in December 2010, appeared to be each wearing a silver band on their respective ring fingers to walk the red carpet arm in arm at the awards ceremony.
His and hers: The pair are known for keeping quiet about their relationship but may have revealed a big secret at the Oscars
Natalie wore hers alongside her diamond engagement ring while Benjamin's ring stood out on his otherwise bare left hand.
The rings worn by the actress and her Black Swan choreographer beau suggest the pair may have recently married in secret.
A representative for the 30-year-old star was unavailable to comment.
The big reveal?: The rings suggest the engaged couple may have recently tied the knot in secret
At last year's Oscars Natalie was heavily pregnant and had the pressure of being a best actress contender.
But it was a different story for the star last night as she waltzed on to the red carpet at the Academy Awards care-free.
The actress put her svelte post-pregnancy figure on show in a red polka-dot dress, eight months after giving birth to son Aleph and a year after she took home the best actress gong for her movie Black Swan.

And hunky Frenchman Benjamin stood by her side as she made her grand return to the Oscar red carpet.
Last year Natalie was resplendent in regal purple Rodarte at the 2011 Academy Awards as she took home the Best Actress trophy for Black Swan.
But this year, the actress could finally let her hair down now that the pressure of winning an Oscar no longer rested heavy on her head.
