Lennon & Maisy's cover of Charli XCX's 'Boom Clap' is giving us chills

Remember Lennon & Maisy? The adorable sibling YouTube stars who stole our hearts with their beautiful covers, like this version of Call Your Girlfriend played with yogurt cups?

Well the adorable duo has been spending some time over on ABC's Nashville, but it seems they have returned to their YouTube roots, posting the first video on their page since March of 2014, and it's about as lovely as we would expect. The sisters covered Charli XCX's Boom Clap (you know the one from The Fault in Our Stars), and it was pretty much perfect.

Here's to hoping they upload more videos in the future. We think they would do an amazing job with Rihanna's FourFiveSeconds.
