The CMT Awards are aiming for big collaborative moments this year: Dierks Bentley will perform with Elle King (the two duet on Bentley’s new album), Fifth Harmony teams up with Cam, Billy Ray Cyrus with Cheap Trick, Blake Shelton with the Oak Ridge Boys, and Keith Urban with both Brett Eldredge and Maren Morris. Today it was announced that Pitbull — who appeared on Keith Urban’s “Sun Don’t Let Me Down” earlier this year — and Leona Lewis will also join forces with Cassadee Pope during the show. Carrie Underwood was added to the lineup as well. She will perform “Church Bells,” which she performed at the ACMs and the ACCAs in April.
