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):
There were a lot of brand new acts showing their stuff at the Billboard Music Awards this year!
But Jennifer Lopez decided it was time to show these kids how it's done!
Ch-ch-check out the video (above) to see Jenny from the Block rock the BMAs, with a little help from Pitbull!
We guess Pitbull is a firehouse dog because J-Lo is really working that pole!
