Luke Bryan chats with ET’s Cassie DiLaura in Las Vegas after rehearsals for his performance at the 57th Academy of Country Music Awards. The singer talks about performing his song ‘Buy Dirt’ with Jordan Davis and what it’s like returning to the award show after not attending last year when he won Entertainer of the Year. Bryan also opens up about wrapping up his Vegas residency and what it was like seeing his fellow ‘American Idol’ judge, Katy Perry, bring down the house in her own residency show. The country crooner then reveals that his mom can’t get enough of Sin City! The 57th Academy of Country Music Awards will stream on Prime Video on March 7 at 8 p.m. ET / 5 p.m. PT.
