Niall Horan shows off his naked bum complete with a 'tattoo' of James Corden's face

One Direction singer has previously joked his backside is "too squidgy" to be inked, but comedian Corden obviously had other ideas.

Those omniscient One Direction fans might remember when Niall Horan revealed he could never get a tattoo on his bum - because it's "too squidgy".

But it didn't stop James Corden persuading Niall to get his face stuck on his cheek for Sky panel show A League Of Their Own.

To be fair, it's not the first time the comedian has put his face to a load of crap - just look at the tragic Horne & Corden sketch show for example.

The cheek-to-cheek semi-permanent bit of, er, art apparently took three weeks before being totally removed.

The 19-year-old avoided total embarrassment when forgetting to TURN OFF his webcam after an impromptu online video session with his fans.  

Unaware the camera is still streaming live footage to more than 100,000 fans over the world the One Direction singer hugs a mystery female.

It could have been worse, that’s for sure.

In the final moments, Niall says his goodbyes and waves off the viewers as it appears he attempts to close down the Twitcam live link after hearing a buzz at the door of the apartment.
