Did Rascal Flatts turn into Milli Vanilli at the ACM Awards, lip syncing their latest hit 'Remind?'  There's only one video of their performance on YouTube and it's hard to tell.  However, the lack of videos may be a telling sign. Another sign is, how close the performance sounds to what we play on the radio.

UPDATE: Rascal Flatts says they DID lip sync after Gary Levox lost his voice.  Instead of cancelling, the guys didn't want to let fans down and decided to go ahead with the performance.  'We've never done it before and we're obviously not very good at it,' said the guys. You can say that again.

The performance upset fans who tweeted their disappointment!

 

Watch and be the judge yourself.

You can see the full performance at PerezHilton.com, who also thinks they lip synced.
