Luke Bryan is sorry he wrote anthem lyrics on hand

Country singer Luke Bryan performs the national anthem before the 83rd MLB All-Star Game at Kauffman Stadium on Tuesday in Kansas City. He had written lyrics to the song on his hand so he wouldn’t ‘mess up.’

NEW YORK -- Luke Bryan apologized for his performance during major league baseball's All-Star game.

The country singer admits that he checked the lyrics he had written on his hand while he sang the national anthem Tuesday night. He also checked his watch.

In a series of tweets Wednesday, Bryan says he's sincerely sorry if he offended anyone. He says he just wanted to make sure that he didn't mess up and that his singing came from the heart.

He also said he checked his watch because he knew a stealth bomber was going to fly overhead as part of the festivities, and he started a little late.

Bryan sang the anthem before the National League blew out the American League 8-0 in Kansas City.
