Which celebrities/famous people who have/had more than 1 year engagements prior marrying?

My fiance and I of 3 years are having a 2 year engagement, we're marrying July 23, 2011. We've decided to do this because we want to pay for our wedding independently and to have an easy going planning (I'm nt going to be a bridezilla or go overboard with the decor either). I would like to have some examples of well known people who have had engagements longer than a year as an inspiration :D
