Watch Nina Dobrev Dominate At Giant Beer Pong

Nina Dobrev: secret frat boy.

Nina Dobrev revealed a hidden talent for beer-ponging when She stopped by "The Tonight Show" Tuesday, coming back from a two-point deficit to beat Jimmy Fallon at his own game.

The "Vampire Diaries" actress struggled at first to sink a volleyball into a formation of giant-sized solo cups, downing two (ordinary-sized) cups of beer as penance in what was setting up to be an embarrassing shutout. But then, riding on a golden wave of liquid courage, she found the strength to come back and sink one, two, and then three shots, as a shocked Jimmy had no choice but to empty his shame-cups one by one.
