Jesse McCartney Blames Nerves For Forgetting National Anthem (Video)
McCartney has since taken to his Twitter, blaming nerves for his embarrassing mistake.
He wrote, "Here at the Nascar race! So much fun! Can't believe I forgot the words to the Anthem! I've performed it 100 times. Bad nerves today I guess."
McCartney isn't the only star to mess up the National Anthem - Macy Gray, Anastacia and comedienne Roseanne Barr have all forgotten the lyrics to the song on public stages.
