Cassadee Pope and Avril Lavigne

Cassadee Pope may top iTunes charts with covers of country songs on The Voice, but she’s a pop-rocker at heart. With her final performance before the winner of season 3 of the show was announced tonight (December 18), Cassadee lived out a dream by performing a duet with her pop-rock idol, Avril Lavigne. The ladies joined voices on Avril’s hit ballad, “I’m With You,” with delicious results.
