One Direction Perform ‘Best Song Ever’ on ‘America’s Got Talent’


One Direction is at a fever pitch!

The British boy band’s documentary, This Is Us, will hit theaters on Thursday, and in preparation, they performed on America’s Got Talent on Wednesday night … as the fans in the audience screamed like crazy (some even looked like they were crying).

Afterwards, One Direction — who were discovered on Britain’s version of The X Factor — dished on their new movie to AGT host, Nick Cannon.

“It’s a great chance for the fans to see us .. backstage and behind closed doors,” explained Harry Styles.

“There are plenty of topless scenes,” joked newly-engaged Zayn Malik.
