With speculation swirling on Twitter, the country crooner, 55, admitted backstage that he lip-synced his performance of "Ask Me How I Know" before winning the night's highest honor for the second year in a row (and sixth time overall), per People magazine.
However, a different person pointed out: "God bless you Garth I don't care if you lip sync the song you where sick that happens don't let people bring you down and congrats on entertainer of the year @garthbrooks".
Another tweeted, "Garth Brooks is REALLY bad at lip syncing", while a third posted, "Worst lip syncing I've ever seen".
You might have noticed awkward timing during Garth Brooks' performance at the CMA Awards and chalked it up to the typical delay that is built into live television shows.
With a seven-night run in Spokane, Washington, starting November 9, the superstar said he was doing his best to save what voice he had left for those performances.
Brooks added that he was "trying to save what will be on stage tomorrow night [and] for another seven nights".
Paisley then dedicated the 51st CMA Awards "to all those we've lost, and to all of those who are still healing".
"Getting this presented to me by the entertainer of a lifetime, I thank you", he said, after receiving the gong from Reba McEntire. "We made a decision to lip sync it because my voice just isn't going anywhere, and we wanted to represent country music the best we can".
"Two words: Taco Bell. that's where we were a year ago tonight", he told "Good Morning America" of how he celebrated last year. "I'm so happy, happy for the band and crew".
