Smith soaks bartender in champagne at Vegas after-party

To celebrate their first title in franchise history, the Cleveland Cavaliers held their championship-winning after-party at XS Nightclub in Las Vegas.

Mercurial shooting guard J.R. Smith appeared to be having the most fun of the group, pouring an entire bottle of champagne on a bartender.

Smith's attire, or lack thereof, eventually rubbed off on his teammates, as Iman Shumpert joined him in going shirtless.
