Just before he was presented with the award, however, Brooks took the stage to perform "Ask Me How I Know" from his latest album Gunslinger, and viewers were quick to notice that he was lip-syncing.
"Getting this presented to me by the entertainer of a lifetime, I thank you", he said.
Brooks, who won his first CMA for Entertainer of the Year in 1991, noted that he's now having some of the best years of his career while doing it on his own terms. All you guys down here on the front row: We can all agree on one thing.
"Right now we're in the middle of 12 shows in 10 days", he told Fox News "We've got four days (where) we're doing two shows a day". "We made a game-time call on whether to sing to a track or lip-sync", the singer said. "My voice just isn't going anywhere, and we wanted to represent country music the best we can".
Garth admitted he did lip-synch, saying that he was considering using a track for his performance before the show. Some years, that family gets a little more challenge than others and they'll rise for it. "They work their asses off", he says.
Yearwood and Brooks then celebrated the win on Twitter.
Brooks and his wife, Trisha Yearwood, have been on the road since 2014. "Sleep", he said. "I just think we're all going to sleep for a while". We call it being wired and exhausted.
President Trump isn't the only one lighting up Twitter after Wednesday's CMA Awards.
