But Kim Kardashian's journey to marital, domestic bliss has not been without romantic bumps in the road. Some of them notorious.
We all remember her 72-day marriage and the Kim Kardashian sex tape, but she was in some other high-profile relationships, too.
Here's a look back at Kim Kardashian's dating history ...
T.J. Jackson, Michael's nephew, was Kim's first love. It's believed that he was her "first" in the physical sense as well.
Kim's forgotten husband, music producer Damon Thomas, was married to her from 2000-04. Yes, those dates are correct!
Nick Cannon and Kim Kardashian were a thing in 2006-07. She's been around awhile!
The Game said it himself recently. He has never dated Khloe Kardashian, despite the frequent rumors to that effect ... but he did have a thing with Kim for awhile. Who knew?!
Ray J. One name and one additional letter say it all. When he recorded the Kim Kardashian sex tape, a superstar was born.
