English musician and composer Paul McCartney will marry US heiress Nancy Shevell Sunday. This is going to be his third marriage.

The event will take place in a civil ceremony in London amid close friends and family. It has been reported that the vows will be exchanged at the Westminster Register Office in London.

According to Daily Mirror, there will be 30 invited guests and a reception will be held in McCartney's garden.

The wedding is in keeping with the way Paul and Nancy have conducted their entire relationship - low-key, understated and fueled by goodwill. Neither of them wanted a huge fuss made and the main priority, for both, was family, Daily Mirror quoted a source close to the star as saying.

After the low-key marriage, the couple is expected to visit the Caribbean later this month for their honeymoon.

The Sun reported that Shevell's wedding dress had been designed by Paul's daughter Stella McCartney.
