And despite wearing a fitted dress and heels, the Vampire Diaries star became the champ when she beat US host Jimmy in their close knit game.
Equipped with giant frat cups and volleyballs for ping pong balls (we so need to whip this out at our next summer party...), Jimmy got off to a cracking start slam dunking two shots and forcing Nina, in beer pong spirit, to down her drinks.
But the beer only seemed to help her game as Nina came back fighting to level with the chat show host. Playing her last ball like a pro, the 25-year-old made hitting the target look easy as she successfully sank her shot.
And making sure Jimmy got his just desserts, Nina was more than happy to chant for him to drink as he shamefully finished off his last beer-filled cup.
Nina looked gorgeous for her TV appearance wearing a beautiful black midi dress with a gold print and patterned heels.
Chatting to Jimmy, Nina appeared on the show to promote her upcoming film Let's Be Cops, where she stars alongside New Girl actors Jake Johnson and Damon Wayans Jr, before all the fun and games began.
Now where can we get our hands on a giant beer pong set... Oh, and of course, drink responsibly!
