It was definitely Scotty McCreery's voice this morning during a special performance at the Macy's Thanksgiving Day Parade -- but there was one big problem ... Scotty's lips weren't moving.
It's no shocker singers lip sync at the big parade -- but this morning, the newly-minted "American Idol" winner made it painfully obvious ... when he started "singing" one of his songs just a tad too late.
Check out the clip. It's pretty damn awkward.
