Natalie Portman has got married, her ring-designer has confirmed.

Jeweler Jamie Wolf confirmed the actress and choreographer Benjamin Millepied - who met on the set of 'Black Swan' in 2009 - have tied the knot after speculation increased when they were spotted wearing rings at the Academy Awards in Hollywood on Sunday.

Jamie - a dancer friend of Benjamin's - told Us Weekly magazine: ''I designed the rings worn by Benjamin Millepied and Natalie Portman. They were made with recycled platinum and conflict-free diamonds.''

Details about when the couple - who have an eight-month-old son Aleph - tied the knot are yet to have been revealed.

Jamie also designed the 30-year-old actress' engagement ring - an antique diamond surrounded by conflict-free stones and made of recycled platinum - and previously revealed the 34-year-old actor was determined to ensure he got ''everything right'' about the band.

The jeweler explained: ''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.''

The pair got engaged in December 2010 before welcoming Aleph last June.
