Perhaps the fourth time is the charm for Roger Waters, as the Pink Floyd singer-bassist plans to tie the knot with bride number four next year. Waters and his longtime fiancee, filmmaker Laurie Durning, will walk down the aisle in 2012 sometime before Waters resumes his Wall Live tour.

Why now, after seven years of being engaged? “It just seems like a good time to do it before the tour," Durning told The New York Post. And although Roger Waters certainly is rock 'n' roll royalty, don't expect an over-the-top extravaganza like the (second!) wedding party recently hosted by Paul McCartney and his new wife, Nancy Shevell -- Durning says she is only inviting close friends to the “private and low-key” ceremony.

Is that her way of telling us our invitation is not in the mail?

If they do plan to get married before Waters hits the road, the wedding could be happening sooner than later. Waters is scheduled to kick off a busy year of touring on Jan. 27 in Perth, Australia. He currently has dozens of dates scheduled through a July 14 gig in Philadelphia.

The couple is said to be in the market for a new engagement ring, since the bride-to-be misplaced the original ring after Waters proposed back in 2004.

Rogers has three children from his previously relationships, including son Harry Waters, who has been touring keyboardist for his father's band since 2006.
