While this will be West's first trip down the aisle, Kardashian was married twice before - to music producer Damon Thomas in 2004 and NBA Player Kris Humphries in 2011. West, 36, and Kardashian,33, have one child together, daughter North West, born shortly after a judge finalized Kardashian's divorce from Humphries. That marriage lasted 72 days.
