(CNN)The fight between Floyd Mayweather and Manny Pacquiao promised to be the fight of the century.

But one of the events before the fight grabbed a lot of attention on social media late Saturday.
Oscar winner/singer Jamie Foxx performed the national anthem before the crowd -- and the reaction at home was decidedly mixed, to say the least.
Twitter trashed Foxx's performance, in which he had to remove his earpiece early on in the proceedings, implying some issues with staying on key with the organ accompaniment.
    "The real fight was between Jamie Foxx and the national anthem," said "Prince."
    "Jamie Foxx's national anthem had more twists and turns than the fight," tweeted "Funny Tweets."
    "Did he sing hallelujah at the end???" asked Robert Glasper. (Yes, yes he did.)
    Even Paul Stanley of rock band Kiss weighed in: "What was THAT?!?"
