"I'm always flattered that these people that I consider heroic artists and defining artists, I can't believe they know my name," he gushed at the CMT Artists of the Year taping on Wednesday night in Nashville. "I still get starstruck around people like her."
Twain was honored with the Artist of a Lifetime award, complete with a tribute performance by Kelsea Ballerini, Jill Scott and Meghan Trainor, while Bryan was presented his fifth consecutive Artist of the Year trophy. The special will re-air throughout the weekend on CMT.
"It just makes me reflect on a lot of years of being really blessed and a lot of support from the fans out there," he told ET. "This is a fun night, it's a laid-back night."
Bryan was recognized for his stellar 2016 alongside Carrie Underwood, Chris Stapleton, Florida Georgia Line and Thomas Rhett, as well as newcomer Ballerini. In a full-circle kind of moment, the 23-year-old couldn't help but fangirl over Bryan during her interview with ET!
"Oh my gosh, Luke Bryan is right there and I'm about to pass out," she joked. "It's very normal for me to be very fangirly."
Ballerini sang "Any Man of Mine" during the show's Twain tribute, but even before the performance, the iconic 51-year-old performer gave Ballerini her blessing as a promising female representative for the country music community.
"Carrie's been holding this torch for a long time," Twain said, "and now there's a slew of really mega talents. Kelsea, what can you say? She's got a mega voice and she's going to be singing one of my songs tonight, so I'm really thrilled."
