Miley Cyrus' MTV Video Music Awards performance Sunday night likely left many shocked and even puzzled, but no reaction was better than that of Rihanna and the boys of One Direction.


Cyrus performed her summer hit, "We Can't Stop," and then stayed on stage to perform "Blurred Lines" with Robin Thicke. The act included giant teddy bears, wild twerking, some latex underwear and lots of tongue. She also took some time to grind on Thicke (who is a 36-year-old husband and father) and pretend to lick his chest, before running off with her foam finger.


While the 20-year-old pop singer was performing, the camera panned to the crowd and landed on Rihanna and One Direction, who were sitting near each other inside the Barclays Center. The R&B superstar, her posse and the boys of 1D were not impressed.

Rihanna's blank expression spoke volumes, while Harry Styles and his furrowed brow seemed very perplexed. Needless to say, they probably weren't the only ones. It's not everyday you see a former Disney darling running around on stage in pigtails and a onesie slapping butts and twerking.


Others were downright disturbed.
