Natalie Portman and her fiance Benjamin Millepied are to wed in California this summer (12).

News of the couple's engagement emerged in 2010 and the pair sparked rumours of a secret marriage in February this year (12) when they were spotted wearing bands on their ring fingers at the Academy Awards in Los Angeles.

However, sources tell In Touch Weekly that Portman and Millepied are planning a low-key ceremony on the Californian coast on 5 August (12).

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

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