Game 5 of the World Series on Sunday left yet another singer embarrassed after flubbing the lyrics to the "Star-Spangled Banner."

The 42-year-old country crooner Aaron Lewis, lead singer of Staind, sang the National Anthem but made a little mistake that was hugely recognizable. "What so proudly we hailed were so gallantly streaming," he crooned.

What was missing? The lyrics actually read: "What so proudly we hailed at the twilight's last gleaming."

After the Twitterverse caught wind of this mess-up (Americans love a National Anthem flub!), Lewis apologized in an over-the-top Facebook message.

"All I can say is I'm sorry and ask for the Nation's forgiveness. My nerves got the best of me and I am completely torn up about what happened," he wrote. "The Star-Spangled Banner means so much to so many, including myself. I hope everyone can understand the intensity of the situation and my true intent of this performance. I hope that the Nation, Major League Baseball and the many fans of our national pastime can forgive me."

The apology continued, "I think it's safe to say that his apology is accepted by everyone and he didn't really need to apologize in the first place. We've seen many people have problems with the national anthem before.But still, a classy move by Lewis, who obviously loves America."

While Lewis didn't have a great night, the San Francisco Giants did! The team beat the Kansas City Royals, 5-0.

Lewis isn't the first to have a flub this year. Gwen Stefani pronounced Stephen Colbert's name wrong at the 2014 Emmy Awards, and the late-night host gave his reaction to the mispronunciation to ET.
