The internet has gone into something of a craze after a video of One Direction stars Harry Styles and Niall Horan getting close on stage emerged online.

The pop group were playing in Texas on Sunday (June 24) as part of their headline North American tour.

A video has emerged from the gig showing Styles leaning into Horan during their hit track 'What Makes You Beautiful'.

It seems as if Styles was whispering something into Horan's ear, but the clip looks close to a kiss.

Elsewhere in the video, Zayn Malik also lifted up Styles' shirt as the gig got hot and sweaty.
