(CBS/AP) Luke Bryan says he is sorry for consulting the lyrics to the national anthem written on his hand during his performance at the MLB All-Star game.
The country singer admitted to checking the lyrics, but also checking his watch during his performance on Tuesday night.
"I had a few keys (sic) words written down to insure myself that I wouldn't mess up.. I just wanted to do my best. I promise it was from the heart," the singer wrote on Twitter.
He continued saying, "If I offended anyone with my approach I sincerely apologize. Anytime I sing the anthem it is an honor and my heart beats out of my chest. I did check my watch because I knew the stealth bomber would fly over 2 minutes in and I knew a started a little late."
Bryan sang the anthem before the National League blew out the American League 8-0 in Kansas City, Mo.
