Kristen Kelly turns lemons into lemonade with her debut single, "Ex Old Man," which was inspired by her divorce.

"This is the true story about the fact that I have an ex-husband and an ex-best girlfriend," says the Texas native, who is making a name for herself as one of the most promising new singers in country music. "I found out by going home to get some of my stuff, and my best friend's car was parked in our driveway, and half of her stuff was moved in to my house. I wrote her a little note [that said], 'I hope you enjoy bathing in my bathtub, sleeping in my bed and living in a house that I designed and built!' I tried so hard to get so mad, but I just couldn't do it. This is a true story about how it all played out."

Kristen's "Ex Old Man" is the first debut single by a female artist to ever be the most-added song on the Country Aircheck chart. Watch her perform the song in a special, behind-the-scenes video below.
