Heading out to Vegas is always fun. Naked Justin Bieber took some time out on his Vegas vacation to do some wine tasting. You see NJB here with a lovely Pinot Grigio. After a few swigs of this he started belting out, “All the pinot, pinot grigio girls pour your heart out. Watch your blues turn gold…” We reminded him that he’s not Lady Gaga and to chill out. Secretly, we enjoyed the show, but hey, NJB, remember to keep it classy!
