Listen to Ellie Goulding on iHeartRadio | Listen to Justin Timberlake on iHeartRadio

Much like the rest of his "20/20 Experience" hits, Justin Timberlake's "Mirrors" has become extremely successful. You can't turn on the radio without hearing it. What could be better than Justin singing it? How about Ellie Goulding!

This week Ellie posted a photo to her Instagram account of herself and Justin, with adorable word bubbles written in, of Ellie asking Justin if she could cover his hit song. His response? "Sure EG"

Ellie covered "Mirrors" only a day after her Instagram post! And she sounds like an angel! Watch below:
