UPDATE 3:21 P.M. EST: Kanye West was spilling all sorts of tea about Jay Z.
He could be heard yelling mid-concert:
Yikes! You can watch the tense moment for yourself (below):
We've seen MattyB do some amazing covers! But now he's taking his talent all the way to Korea to learn the ancient art of Gangnam Style!
Ch-ch-check out the video (above) for MattyB's runaway take on PSY's runaway hit! All the babysitters are doing it!
And while you're at it, look close for a cameo by an extremely handsome musical sensation you might know!
…No, we're not talking about Nick Jonas! Ha!
