Will Smith and Family Jaw-Dropping Reacts To Miley Cyrus Twerking In her Undies At The MTV VMA's -- Video Inside

 Miley Cyrus thrusted, twerked, and got sexy with Robin Thicke during her showy VMAs performance this evening in Brooklyn, while just minutes earlier Lady Gaga showed off her own ridiculous moves.

During the audacious "We Can't Stop"/"Blurred Lines" and "Applause" medleys, the cameras cut to some of the audience reactions. Drake looked to be a little bit distracted during Miley, but Will Smith and his kids, Willow and Jaden, were literally mouth agape watching all the jaw-dropping moves.

You should weigh in on all the VMAs performances and enjoy a smile watching the Smiths take in everything the VMAs had to offer.
