If you saw the Legacies episode with the Salvatore School's talent show, then you're probably wondering if Kaylee is actually singing, and the answer is absolutely. The decision to put in this bit happened with a little help from Kaylee's manager, who sent Legacies producer Julie Plec a video of 14-year-old Kaylee performing before the show even began filming. Seriously, just watch her cover of Imagine Dragons' "Radioactive."
