They're not the only member of One Direction who've considered getting inked, although we've apparently got Niall Horan's squidgy arse to thank for the fact that he's yet to join that particular club.
“Harry and Zayn are going at it with the tattoos," Niall told the Sun. "They are covered now. Harry seems to have a different one every day."
But the fact that the other lads are such big fans of getting inked seems to have rubbed off on Nialler and he even got as far as the tattoo parlour before wussing out.
“I decided to get Made In Ireland in green on my arse cheek and I went to the place in LA where they do it," he explained.
"Me and the boys went in and they said they wouldn't do it."
“They said the skin on your arse is too squidgy. It needs to be tight.
"I suspect they did me a favour. It wasn't the best idea in the world.”
To be fair, we wouldn't want to be the ones responsible for making Niall cry either, but for the chance to stare at his bum cheeks for a couple of hours, we'd definitely be up for a go.
Don't worry though Nialler, the rest of 1D think you're beautiful just the way you are..
So what do you think about all this? Glad he didn't go through with it or would that have made your ovaries even more of a fan of Nialler?
