Quintavious Johnson and Jennifer Hudson duet on America's Got Talent 2014 Finale (VIDEO)

Quintavious Johnson and Jennifer Hudson performed a duet on the America's Got Talent 2014 Finale.

Jennifer Hudson kicks things off with her new single, 'It's Your World', and it's a very dancey track. Reminded me of Donna Summer, actually, as this was straight-up disco, from the beat to the dancers in sequins and frizzy hair behind her. Even the dance movements seem straight out of Studio 54. It's a catchy song, although it feels like a bit too much of a throwback to be a hit. But you never know.

Quintavious comes out onstage for (what else?) 'And I Am Telling You I'm Not Going', and I find myself wondering if J-Hud ever gets tired of singing this on reality talent show finales with contestants. Either way, I'm nowhere near sick of hearing it, as Quintavious absolutely SLAYS this. It was easily his best vocal, in my opinion. This kid is incredible, going note-for-note with Jennifer Hudson, which is crazy for a 12-year-old to accomplish.

In the post-performance interview, Jennifer talks about how talented Quintavious is, even forgoing promoting her new album just to gush about how great the kid is, and I don't blame her one bit.
