Britney Spears' sons will be the ringbearers when she marries third husband Jason Trawick this summer.

The singer will tie the knot with her former agent later this year and she wants Sean Preston, six, and five-year-old Jayden James - her boys from her marriage to second husband Kevin Federline - to play a big role.

"It's going to be a very intimate wedding with only immediate family and very, very close friends. It will probably be a destination wedding in a very warm, tropical location. There is absolutely no drama with the planning of the wedding and Britney will probably wear an off-white dress that will show off her killer bod. Britney's sons are absolutely going to be a part of the ceremony as ringbearers, and Jason has something very special planned for the boys that will take place during the wedding," a source said.

However, Britney, 30, won't be marrying Jason until she has settled several lawsuits against her as she wants to start married life with a clean slate.

"Britney doesn't want to get married until all legal matters have been dealt with. She wants to begin her life with Jason on a fresh clean slate," the source added.

As well as being married to Kevin, Britney also had her first marriage to childhood friend Jason Alexander annulled after just 55 hours in January 2004.
