It's not every day that kids get to sing on a stage as legendary as the Opry, but Lennon and Maisy aren't just any kids. The Canadian cuties are regulars to the esteemed venue these days, and their rendition of Johnny Cash's 'Ring of Fire' from 2013 proves they're musically wise beyond their young years.

Now that they're stars on ABC's hit show 'Nashville,' the Lennon and Maisy Stella are somewhat of household names -- but don't let their acting ability outshine their true talent: singing. The sisters got the honor of playing the Opry during CMA Fest in 2013 and were both thrilled with the opportunity. Their voices didn't disappoint as they sang and played on the iconic circle, harmonizing and impressing the crowd. Prepare to be amazed!
