Harry Styles vs. Piers Morgan Prank [WATCH]: 1D Cutie Pulls Down CNN Star's Pants During Niall Horan Charity Soccer Game, Seeks Twitter Revenge!

One Direction crooner Niall Horan hosted a charity soccer event to help raise awarness of the Irish Autism Auction on Monday (May 26). Fellow bandmate Harry Styles took the field to support the cause - and managed to get some major laughs while doing so!

At one point during the game, Styles ran up to opponent Piers Morgan on the sidelines and unexpectedly pulled down his pants - in front of the jam-packed crowd!

Thankfully, the hilarious "pants-ing" prank was captured on video!

Viewers can hear spectators screaming after Styles holds up his hands in victory while running away from the pants-less CNN host.

But all in good fun! The former "America's Got Talent" judge later tweeted:

@piersmorgan: "Chilly > RT @imamaliker: @piersmorgan how did it feel when harry pulled your pants down?"

@piersmorgan: "Revenge will be sweet @Harry_Styles... watch your shorts. #1D."

So watch out, Styles! 1Ders would probably enjoy such revenge!

Embarrassing for the 49-year-old British television journalist, but at least he didn't bare too much skin!
