Natalie Portman is reportedly planning to get married in August.

In February, the actress sparked rumours she had tied the knot with fiance Benjamin Millepied. She was spotted wearing what appeared to be a wedding band in addition to her diamond engagement ring, fuelling speculation she had secretly wed before the Oscars. However, it has now been suggested that the couple are preparing to exchange vows in an intimate ceremony in California on August 5.

"Natalie and Ben will marry in Big Sur," a source told In Touch. "It's one of Natalie's favourite places - whenever she needs a break from LA, she comes here to escape."

The insider also revealed that Natalie and Benjamin began wearing rings before the arrival of their one-year-old son Aleph last year.

"Natalie and Ben exchanged rings in private prior to Aleph's birth," the source explained.

It was widely reported the couple had tied the knot in February, with a jeweller friend of Benjamin revealing she had made customised matching rings for them.

However, In Touch insists they will finally make it official in front of 60 guests in August.

"This wedding is for their closest friends and family," added the source. "It will be a very relaxed affair. They're not sending out invites. Natalie may not even buy a new dress!"

The couple began dating in 2009 and met on the set of award-winning movie Black Swan.
