Honestly....WHO CARES? Britney is one of the biggest artists in the world and, has she ever sung live? Garth is the king and didn't want to back off from the commitment to perform. Here is the full story:
Garth Brooks took the top honor of Entertainer of the Year at last night's CMA Awards, but also took a bit of criticism for lip-syncing his earlier performance of "Ask Me How I Know."
Garth accepted the award and headed backstage to the press room where he was asked about the rumors on social media that he wasn't really singing. He said the rumors were true and explained, "We’re in the middle of 12 shows in 10 days. Not 10 shows in 12 days, 12 shows in 10 days.
