By now you've probably heard that Beyoncé surprised fans by joining husband Jay Z on stage at a Pre-Super Bowl concert. Blue Ivy's parents performed "Drunk in Love"—the same tune they dueted only six days early at the Grammys—and even hugged and kissed on stage.
While that was all squeal-worthy, the singer's super sexy Roberto Cavalli number probably also caused a few gasps on it's own. Mainly because the sparkling gown featured sheer peek-a-boo paneling which allowed all of the star's famous curves to be very visible. Towering Christian Louboutin peep toes and dazzling Lorraine Schwartz jewelry helped add more wow factor.
