One Direction member Niall Horan turns up the naughty factor with his recent ‘exposure’, if you know what we mean.

The blond heartthrob appeared in the hit British comedy panel game show, A League of Their Own, where host James Corden challenged him.

“We made a thing on the show that he’s the only member of the band without a tattoo,” says Corden to the Sun.

The host continues, “I said to him, ‘We’ve got this idea of putting a tattoo of my face on your body.’ Niall went, ‘You should put it on my arse.’”

Well, they did.

A temporary tattoo – thankfully – of James’ face was stuck on Niall’s left butt cheek, and he even bragged about it in front of the cameras for Directioners to feast on.

Though the stint was already months old, the mark wasn’t as easy to remove as he thought.

“It took him three weeks to get rid of it,” Corden reveals.

“He sent me updates every week, with a photo of my fading face on his arse, saying, ‘It’s still not gone yet.’”

We say, the 19-year-old looks ready for some “cheeky” action!
