The duo, who can only be described as the hipster Civil Wars, wowed the judges with their simple take on the pop song. Demi and new judge Kelly gushed over the couple, while fellow newbie Paulina declared herself “a believer.” As for Simon? He called the performance “cool” and “quirky.” Watch their performance below!
But the wholesome duo weren't the only reality singing competition show hopefuls to cover the song on TV recently. Voicefinalist Melanie Martinez, from Baldwin, N.Y., impressed the judges with a folksy twist on “Toxic” in The Voice Season 3 Blind Auditions on Sept. 17, 2012. Adam, Cee Lo, and Blake all turned their chairs around for the talented 17-year-old, but in the end, Melanie picked Team Adam!
