Kim Kardashian's romance with NFL star Reggie Bush will not be heading into overtime. The couple have broken up after more than two years of dating, Kardashian's rep confirms for TVGuide.com.

A source says the split was a mutual decision and stemmed from schedule conflicts that kept them apart much of the time. Most recently, Bush, 24, invited Kardashian, 28, to accompany him to New Orleans, where he is due to report for preseason training. Kardashian, though, needs to stay on the West Coast to film the new season of Keeping Up with the Kardashians.

Wedding talk often circled the couple, who first began dating in 2007. Kardashian told TVGuide.com in May, "People ask us [about marriage] all the time. Of course we talk about marriage, but who knows when that's coming."
