The `Toxic` 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. A source told RadarOnline.com: "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." 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. The source added: "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." 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.
