Given her recent nuptuals (and soon to be recent denuptualizing), I am setting the line for number of Britney Spears marriages at five. To wit:

Wedding #1: the one to this guy from home, who will cash in the last of his 15 minutes of fame in 2005 on either Celebrity Mole or The Surreal Life.

Wedding #2: another quickie to a guy in her show, more likely a musician than a dancer or tech. It'll go more than a day, less than a year.

Wedding #3: this will be the one that is wistfully remembered in her autobiography I Wasn't That Innocent as the "real" marriage of the bunch. I'm thinking restauranteur. They'll go 5-6 years, with a couple of kids.

Wedding #4: a grab at celebrity, an actor TBA. Two years, tops.

Wedding #5: Britney marries a kindly older man, retired. Parallels to Anna Nicole Smith will be raised, but he won't be that old. They'll average about three weeks together a year until he passes on about nine years into the marriage.

That should take Britney up to about age 40. By 45 she'll start dating the eldest son of Ashton Kutcher and Demi Moore.
