Niall Horan, James Corden

If you thought Justin Bieber's naked butt was the only behind you'd get to see today, boy, you were wrong.

Niall Horan bared his behind to show off a tattoo (temporary, thank goodness) of comedian James Corden's face!

So why exactly did the 19-year-old boy bander brand his bottom? Well, when James, host of British game show A League of Their Own, learned that  that Niall was the only member of One Direction without any ink, he suggested the singer get a tattoo of his face somewhere on his body.  Then, according to James, Niall not only agreed, but he also suggested to the comedian, "You should put it on my arse!"

Ask and you shall receive, Niall!

"We tattooed it on to his left buttock— it took him three weeks to get rid of it," James revealed. "He sent me updates every week, with a photo of my fading face on his arse saying, ‘It's still not gone yet.'"

Niall found the stunt amusing, grinning as he pulled down his pants and Calvin Klein underwear for a snap. He also tweetied cheekily Monday, "What ya think of the pic of my arse and @jkcordens face?"

James, whose image still remains on the musician's rear, wrote back, "You love it Niall! I think you should get it done permanently!"

Hmmm. Think before you ink, kiddo.

PHOTOS: Niall was smart with a temporary tatt, but these stars' regrettable ink was permanent!
