5. Kim Kardashian and Reggie Bush
The reality star with the ample assets and the saint with a slightly off-kilter halo ended their three year relationship for good in March. As far as why the couple called it quits, there are a few different stories. Life and Style magazine reported that "sophisticated businesswoman" Kim needed a more grown-up relationship that Reggie just couldn't deliver. Another theory is that the New Orleans Saints running back didn't enjoy being in the spotlight of the entertainment industry. And, of course, there's always the homewrecking bimbo theory...cue January Gessart. Rumors the couple were getting back together in October proved to be untrue and in fact, Kim was spotted on the town with Halle Berry's ex Gabriel Aubry and most recently, New Jersey Nets forward Kris Humphries.
