Scotty McCreery, Lauren Alaina

Thanksgiving was not a great day to be a Season 10 American Idol finalist.

Champ Scotty McCreery started off the bad day with a major blunder at the Macy's Thanksgiving Day Parade, where he was to perform his song "The Trouble With Girls" on top of a float. Well, he has more trouble with lip-synching (all performers lip-sync at the parade), missing his cue for the start of the song. His voice blared from the speakers, but his lips didn't move.

Later at the Green Bay Packers-Detroit Lions game, runner-up Lauren Alaina pulled a Christina Aguilera and messed up the lyrics to "The Star-Spangled Banner." During the line, "What so proudly we hailed at the twilight's last gleaming," she stopped halfway through and resumed with "last gleaming."

Alaina owned up to the mishap on Twitter, writing: "Thank you everyone for the kind words. But the truth is I messed up. I'm gonna spend the rest of the day being thankful for all my blessings."

McCreery, however, made no mention of his blooper.
