London, Aug 31 : Pop star Britney Spears is reportedly planning to tie the knot with her boyfriend and former agent Jason Trawick and she wants a low key wedding.

This will be her third marriage."They've decided to have a small, intimate ceremony, not a big media circus. They'd like to say 'I do' by the end of the year," dailystar. co. uk quoted a source as saying.

Spears had previously been married to Jason Alexander (2004) but divorced him just a few days later. In the same year, she wed Kevin Federline. In 2006, she filed for a divorce from Federline with whom she has two sons.(IANS)
