Usher Keeps Roller-Skating at Vegas After-Party Following Halftime Show

Usher's moves from the Halftime show seamlessly floated on over to an after-party -- where he kept on skating ... only here, all eyes were on him and his (maybe?) new bride.

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 ... all while looking pretty slick. Remember, Usher incorporated roller skating into his epic halftime performance, and he's keeping the good vibes going here as well.

The after-party went down at Flipper's Roller Boogie Palace inside Encore Beach Club at Wynn Las Vegas, with performances from Dr. Dre, Snoop Dogg, Diplo and Hardy.

Usher's party also recognized his new album, "Coming Home," and the 30th anniversary of Snoop and Dre's "Gin & Juice." So yeah, SD came out and spit some bars for his old pal.

Other big-time stars who showed up for the bash included ... Andra Day, Big Boy, Brent Faiyaz, Draymond Green, Flavor Flav, Flo Rida, Gabrielle Union, H.E.R, Jermaine Dupri, Justin Hartley, Leon Bridges, Lindsey Vonn, Luke Combs, Ludacris, Machine Gun Kelly, Maren Morris, Megan Fox, Ne-Yo, Pauly Shore, Ray Ray McCloud III, Speedy Morman, TANK, Tiffany Haddish, Too Short, Tim Cook, Victoria Monet, Ying Yang Twins, will.i.am, Winnie Harlow, Zach Bia, and Zane Low ... just to name a few!

Now, eyewitnesses tell us Folks who were there tell us Usher rolled in around 1:40 AM and partied for about 80 minutes ... having fun with a bunch of different people, including his longtime partner, Jennifer Goicoechea, whom he's reported to have married this weekend.

As we reported, Usher and Jennifer obtained a marriage license in Clark County -- and some have suggested they've already tied the knot. If they did, they're keep it low-key for now.

The Flipper’s Skate brand worked with Usher to design the skates he and the skaters wore during the Super Bowl halftime show and to the after party. The skates dropped right after the half time show and you can buy the Flipper’s Quadz by Usher for yourself.

It's unclear or not if Usher and Jenn are, in fact, man and wife at this point -- the details of any purported wedding have surfaced just yet -- but they were being called "newlyweds" at this shindig.

In any case ... lots for Usher to celebrate, regardless. Super Bowl, new album, possible new wife and rave reviews.
