Carrie Underwood and Joan Jett Deliver a Dynamic Country-Rock Set at the CMA Fest

Carrie Underwood brought the house down at Nashville's CMA Fest on June 7, and she did it again on TV. During ABC's Aug. 4 airing of the festival's performances, viewers got to rewatch the 36-year-old singer surprise fans by bringing out special guest Joan Jett of Joan Jett & the Blackhearts for a fiery rock-country set. The two sang some of Jett's best hits, including "Bad Reputation," "I Love Rock & Roll," "Crimson and Clover," "I Hate Myself For Loving You," and "Fresh Start."

Back in June, Underwood took to Instagram to share her excitement over working with the rock icon. "Dreams come true at #CMAFest ! This was mine," she wrote. "Just to be in the same room as @joanjett is really cool . . . to share the stage with her is indescribable! She truly is a legend and is probably the coolest person I have ever met. I was so proud to show her how amazing our CMA Fest crowd is! What a night!"
