Every boyband has to have a bad boy – it’s tradition. The Backstreet Boys had AJ, Take That had Robbie, 5ive had J, O Town had Jacob Underwood (too niche?) and East 17 had, well, all of them.

And now, Zayn Malik is fast becoming the bad boy of One Direction.

Earlier this week, Zayn made everyone gasp by getting snapped having a cheeky cigarette out of the window of 1D’s posh hotel.

And this afternoon, the Bradford boy tweeted a picture of his latest tattoo – an inscription across his collarbone.

Wearing a knit jumper, Zayn pulled the neck down and posed his head off into the web cam, with the sexy little tat on show.

He wrote along with the snap: “For every1 asking what the new tatt means it says be true to who you are’.

Like, totally deep man.

It’s Zayn’s sixth tattoo (as far as we can tell), with the singer already having a yin yang on his wrist, a picture of crossed fingers on his forearm, his granddad’s name Walter in Arabic on his chest and a ‘born lucky’ symbol and playing card on his stomach.

The 19 year old apparently fancies getting a whole tattoo sleeve down his arm… but we’re not sure whether his management would be down with that.

And while Zayn was busy snapping his bodyart, the rest of 1D were tweeting Justin Bieber about being in the recording studio together – potentially making the best pop single of all time. So uncool, man.
