Harry Styles as he stands up and twerks at the Teen Choice Awards 2013

Harry Styles sent Twitter into meltdown on Sunday night after livening up the Teen Choice Awards with a spot of twerking.

The One Direction star was encouraged by the hosts of the ceremony, Lucy Hale and Darren Criss, to take a second in the spotlight.

And given the opportunity to show off his moves, Harry decided to break out the twerk - a dance move which involves moving the hips up and down.
