Calum Hood from the boy band 5 Seconds of Summer (5SOS) has owned up to a naked video that was leaked online.

Hood was playing with the phone app SnapChat when he sent a short video of him exposing his manhood to a female fan. The fan recorded the clip using a second phone and uploaded it to the internet.

Hood took to Twitter and quickly admitted the footage was genuine. He sent a message to his fans saying “Least Ya Know What It Looks Like Now’ and ‘I’m Still Just a Teenage Kid Learning from Mistakes’.

It’s not the first time the pop star has been caught naked, he previously posed for a number of pictures with a degree of nudity.

Hood’s not alone, Justin Bieber, Tom Daley and Disney Star Dylan Sprouse have all been there too.

The full clip has been posted at Perez Hilton.
