Oops! Jesse McCartney was performing the National Anthem Star Spangled Banner Song at NASCAR’s Pepsi 500 race and he forgot an entire line of the song!

He must have been so nervous with so many people around, and we feel so bad for him!

He posted on his Twitter right after the performance: “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”
