Harry Styles 'Twerking' at Teen Choice Awards 2013 [VIDEO]: One Direction Cutie Shakes Booty with Hosts Lucy Hale and Darren Criss, Ex-Girlfriend Taylor Swift a No-Show

Sunday evening's Teen Choice Awards (August 11, 2013) presented fans with several awesome surprises. One of the best "shows" of the evening... 1D cutie Harry Styles busting-out his twerking skills for co-hosts Lucy Hale and Darren Criss! Taylor Swift's ex sure knows how to shake his booty.. and the crowd (as well as his fellow bandmates) loved it!

First, the boys of One Direction opened-up the show with a live performance of their new hit single, "Best Song Ever" -

After taking their seats, Hale and Criss approached Styles for a mini-twerk demonstration. The British crooner was much too happy to oblige:

That got the crowd screaming. And the Youtube pranksters rolling:

Ed Sheeran and LL Cool J's expressions are priceless.

Styles' ex-girlfriend Taylor Swift skipped-out on the awards show this year.... so Harry had to show the "Red" songstress what she was missing.
