Rumours about whether or not Natalie Portman had married her beau Benjamin Millepied in secret emerged after their appearance at the Oscars on February 26th.

While most of us were transfixed by Portman’s svelte figure and red polka-dot dress, some eagle-eyed onlookers noticed that she was wearing a new ring under her diamond engagement ring.

Her Black Swan choreographer partner also wore a plain band on his ring finger raising questions about whether or not the pair had tied the knot in private.

Now their jeweller Jamie Wolf has told US Weekly that the couple are married and she designed the rings.

Natalie Portman’s ring comprises two eco-friendly, ethically-sourced diamonds that fit either side of her engagement sparkler.

Millepied’s is a simple platinum band made from recycled materials as the couple are very environmentally-friendly, with Portman becoming vegan during her first pregnancy last year.

Ms Wolf told the news provider: “Ben was exceptionally thoughtful and dedicated and patient to make sure we had everything right.

“We wanted everything about the ring to speak to things that are important to Natalie.”

More men may soon be looking for engagement rings online as 47 per cent of women are tempted to propose today (February 29th) as it is a leap year but 64 per cent still expect their boyfriends to buy their ring, according to Eurostar.
