Super Bowl LVIII's headlining act hosted a star-studded bash in Las Vegas Sunday night after the big game ... and TMZ has obtained video of Usher cutting a rug on the dance floor, or on the roller rink, rather.
As you can see, Usher has his roller skates on and he's zipping around, doing some break dance moves .
