Keri Hilson has proven herself to be a prolific songwriter of note who’s crafted hits for singers such as Britney Spears. But when it comes to singing or performing live, Keri often misses the mark badly.

Last night, she butchered the “Star Spangled Banner” by forgetting the words during the Lakers vs. Hawks game at Philips Arena.

The crowd gasped audibly when Keri flubbed the line, “What so proudly we hailed… or the ramparts we watched…”. The line actually goes:

    What so proudly we hailed at the twilight’s last gleaming

Every school kid knows that line, which is why the crowd was so astounded when she flubbed it. What was Keri thinking?

Hilson, who spends an inordinate amount of time addicted to Twitter.com, quickly took to the social network to explain what happened.

It is clear that Keri did not practice singing the National Anthem before she performed last night. How can she when she spends most of her waking hours on Twitter? Maybe she was thinking of her next tweet when she flubbed her lines?

Whatever the reason: Keri’s version of the National Anthem will go down in history as the worst ever to be performed at the Philips Arena.

This morning, Keri took to her Twitter account to announce she would be butchering performing the National Anthem again at the Red Sox/Yankees game this (Easter) Sunday.

Hopefully, that was her idea of an April Fool’s joke.
