Jessica Simpson is set to marry her fiance Eric Johnson this December.

The singer and actress - who gave birth to the couple's first daughter, Maxwell Drew, on May 1 - will tie the knot with the former NFL star on the Hawaiian island of Kauai on December 12.

A source told Life & Style magazine: “Jessica and Eric are eyeing the Hawaiian island of Kauai for the reception for around 60 family and friends.”

As well as planning the nuptials, Jessica - who was previously married to singer Nick Lachey - is also organising Maxwell's baptism and is said to have hired celebrity party planner Mindy Weiss for both bashes.

The source added: “Jessica is busy planning two very important events - Maxwell's baptism and her wedding to Eric.”

Jessica and Eric - who began dating in 2010 - had planned to get married last November but had to postpone the nuptials after discovering they were expecting Maxwell. - Bang Showbiz
