Country Singer Aaron Lewis Flubs National Anthem at World Series

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."

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.
