It's pretty much guaranteed that if you cheat on a country singer, you're going to end up the subject of a song. Someone should have told that to Kellie Pickler's now ex-boyfriend, Nashville Predators star Jordin Tootoo. Pickler and Tootoo ignited a romance earlier this year, but that seems to be over now, allegedly thanks to Tootoo's infidelity.

"Jordin knows what he did," Pickler said Monday, according to the Tennessean. She told her audience at a concert in Michigan a lot more, explaining to the crowd that Tootoo cheated on her and that her new "theme song" is Carrie Underwood's 'Before He Cheats.' She even joked on stage that she hoped her ex's teeth were knocked out during that night's hockey game. But the jokes soon subsided to tears as she sang her song, 'Didn't You Know How Much I Loved You.'
