The concert took place on the plaza in front of the Bridgestone Arena and aired live on ABC's "Good Morning America."
Hundreds of fans braved the cold for hours to see country's leading lady.
The first fans arrived at 9:30 p.m. Wednesday night. The furthest came from Ireland.
"Country music is very big in Ireland. We come ever year. We come for Fan Fare in the summer which is warmer and then we come for the CMA Awards," said Roger Ryan, adding, "We were very lucky. We were here earlier so we got to catch Reba in rehearsal so that was worth it."
Reba has a long list of accolades throughout her career that spans three decades. She's the CMA's most nominated female artist, having won seven awards.
She told Nashville's News 2, "I love being part of the CMA. I love being a member and I love being part of their history and it's a great organization it's done a lot for country music."
Reba is a presenter Thursday night with comedian Tim Allen.
"You never know what Tim's going to be doing. I kind of go the straight and narrow, but Tim, he kind of ventures from the script," she said, adding, "You never know what he's going to be doing."
Reba's new sitcom, "Malibu Country" premieres Friday night on ABC.
The multi-talented entertainer says she likes juggling it all.
"I love doing both and so it's just kind of time management, whatever you have scheduled that's what you go work on," she said.
Coverage of the CMA Awards begins with live coverage from the red carpet on Nashville's News 2 beginning at 4 p.m. and online at wkrn.com.
