In the latest sign of just how prevalent Wiz Khalifa and Charlie Puth's "See You Again" has become, country pop queen Carrie Underwood put her own spin on the No. 1 hit during her headlining performance this week at Big Barrel Country Music Festival in Delaware.

The singer caught some fans by surprise when she mashed up the hip-hop track with her own song of the same title. And she even got through some of Khalifa's bars—rather confidently—before she got deterred by her own laughter.
