Video: "Ex Old Man"

Why We Love It: "When life brings you a lemon, make some lemonade and add some vodka," Kristen jokes about her breakthrough hit, which is based on the real-life story of catching her husband (now ex-husband) cheating on her with her best friend. The song's video, making its debut today (Aug. 13), not only brings the story to life but also shows that this promising country newcomer certainly landed on her feet after the scandal -- in some killer high heels.
