Was Jamie Foxx's national anthem that bad?

Jamie Foxx was pumped about singing our national anthem before the big Manny Pacquiao-Floyd Mayweather fight on Saturday night in Las Vegas.

He tweeted photos of himself backstage at the MGM Grand.

He belted it out a soulful, run-filled rendition that ended with a falsetto "hallelujah." But it seemed he wasn't quite in sync with the organ that was accompanying him.

Of course, social media weighed in, and it wasn't pretty.

Watch, listen and see for yourself.
