Sophia Grace is your new #1 girl. She just dropped her new music video "Best Friends" and boy, do 2nd graders know how to party. Sophia and her best friends dance down catwalk have an elaborate shopping spree at Kmart and Sophia throws down some serious rap game. Whether or not the video was intentionally hilarious, it had us laughing pretty hard and left us thoroughly entertained. We can't wait for the next one Sophia!
