From The Tennessean:

Luke Bryan, who will co-host the 51st Academy of Country Music Awards on Sunday with Dierks Bentley, had a different sidekick Tuesday night — R&B star Jason Derulo.

The pair filmed “CMT Crossroads: Jason Derulo and Luke Bryan” at The Factory in Franklin. On the show, country music stars and singers from outside the genre take turns singing lines in each other’s songs.

“I can’t express how hard it is to come in and learn these songs in a day and a half,” Bryan said from the stage. “(Jason) is crushing it.”

Bryan said he already knew Derulo’s songs because his children listen to his music.

“They don’t listen to Dad,” he quipped.

Hundreds of fans piled into Liberty Hall at The Factory for the show. The men, both charismatic entertainers, started the taping with Bryan’s hits including “Country Girl (Shake it For Me),” “That’s My Kind of Night” and “Strip It Down,” which took a couple of tries to perfect. Derulo added his signature vocal acrobatics to the sexy ballad, which prompted Bryan to ask, “How you do that?”

When Derulo’s music was showcased, Bryan confidently and comfortably covered his parts on Derulo’s “Talk Dirty,” “Trumpets” and “It Girl.”

“This is crazy,” Derulo said of their performance. Then he told Bryan: “Take us on the road.”

Saving the tour conversation for later, the singers opted to take the audience south — to Georgia for their cover song. They performed a stripped-down version of “Georgia On My Mind” — twice because Derulo said it was fun to sing.

“CMT Crossroads: Jason Derulo and Luke Bryan” has yet to be assigned an air date.

Fans can watch Bryan when he co-hosts the ACM Awards at 7 p.m. Sunday on CBS.
