Fans went crazy after the ACM Awards 2014 about Rascal Flatts and the fact that it was very obvious they were lip syncing on the show. On April 7, TMZ was able to find out the news. They are now admitting that they really did lip sync during the show.
The reason was because Gary, the lead singer, lost his voice. They did not want to cancel on the show and so they decided it was better to lip sync than to just not do it. Obviously they don't do this very often because they didn't really do a good job at it.
Their fans went to social networks really upset about it. Honestly Gary wasn't very good at it so if you watch the video it is very obvious that they were not singing on their own.
The group Rascal Flatts admitted they did it but they also said that they have never done it before. It doesn't sound like they plan to do it at the ACM Awards next year either.
