Just in time for the return of "Nashville," the ABC show's youngest stars have released a new duet -- this time a cover of Charli XCX's chart-topping tune "Boom Clap." It's the first video uploaded to the duo's YouTube page since March of 2014.
Lennon and Maisy Stella's rendition of the hit song is so magical that we can almost guarantee all the hairs on your arms will stand up. Enjoy.
"Nashville" airs Wednesdays at 10 pm EST on ABC.
