You may think you know everything there is to know about One Direction. You may even consider yourself a bit of an expert when it comes to the tiniest details about their lives.

Well HOLD THE FRICKIN' PHONE, because there's one thing you don't know. And this one thing is either going to make your head explode with sheer excitement - or leave you feeling deeply disturbed.

One Direction like to dress up as sexy santas. Of the female variety. Well, they do in the world of Sugarscape photoshopping, anyway.

Let's take a look shall we?

Harry Styles

Here's Harry enjoying a festive night out on the town - note how he's making sure we notice his straightened and highlighted locks by running a perfectly manicured finger through his hair.

Zayn Malik

Zayn prefers to indulge in some quiet contemplation time while wearing his Mrs Claus outfit, often while stroking his pet Zebra. Not many people know this, but Zayn's Badger Quiff (RIP) was actually inspired by his black and white friend.

Louis Tomlinson

Louis Tomlinson is far too sassy to actually wear a Mrs Claus outfit when it's time to get festive. Instead, he likes to sit on Santa's knee and demand all sorts of 'fabulous' presents.

Liam Payne

Liam Payne isn't one to do Christmas solo, oh no - when he slips on that red dress it's time to party with his fellow sexy santa pals. It's a joyus sight to behold, let us tell you.

Niall Horan

For Niall - it's all about being as over-the-top as possible. He's got fake snow, he's got a sledge, he's got a fur trimmed bra... and just out of sight there's an ENTIRE nando's chicken. What else did you think he was gazing so wistfully at?

Which member of One Direction rocks the sexy santa look best?
