The clip marks a fun return to the real-life sisters’ pop-friendly roots. Before they were on TV, Lennon & Maisy, now 15 and 11 respectively, were blowing up on YouTube. Their cover of Robyn's "Call Your Girlfriend" went viral overnight, landing them a spot on Good Morning America and later, The Ellen DeGeneres Show.
Lennon & Maisy returned to Nashville on the show's Feb. 4 midseason premiere but let's be real, Nashville once a week is never enough! The girls have plenty of fun YouTube videos to keep you entertained until next Wednesday.
