We applaud the older of the two sisters in this video for keeping her focus during a cover of Kellie Pickler's 'Best Days of Your Life.' The then-7-year-old not only remains dedicated to the song, but she doesn't miss a step with her choreography. She's a true professional!

Her 2-year-old sister, however.... that's quite another story. She runs around the "stage" like Big Kenny after six bottles of Jolt soda. What can you expect? She's two! Toward the end, little sister does return to finish the song (there's a bit of a tantrum early on), although she trips over the microphone cords and tips over.
