She's now happily married to Kanye West, with a daughter, North, born two years ago and a baby boy, Saint, arriving last year.
But 35-year-old Kimberly Noel Kardashian's journey to marital, domestic bliss has not been without romantic bumps in the road.
Some of them rather notorious.
We all remember her 72-day marriage to the Hump and the Ray J-produced Kim Kardashian sex tape, but that's not even all.
Kim was in other high-profile relationships, too; some you may remember well, others were but fleeting moments in the dating "Game."
Here's a very sexy look back ...
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.
After Ray J hit it first (or more like fourth or fifth), Kim moved on to NFL star Reggie Bush, with whom she had a long-term relationship.
