Liam Payne has become the latest member of the band to get inked, after he unveiled a new design on his arm last night.
The One Directioner has had a line of script tattooed up his left forearm, which was on show as he left London's Funky Bhudda nightclub.
It isn't Liam's first piece of ink though, as earlier this month he and Louis Tomlinson had matching screws etched on their ankles during a trip to Ireland.
Louis - who also recently unveiled a tat of a stickman on a skateboard - tweeted: "So Me and Liam joined the crew yesterday and got two screw tattoo’s on our ankles, now we all have it except Niall! Come on @NiallOfficial."
Liam was out on the town last night after being told he was allowed to drink again after a long-running kidney problem.
The star, who split from girlfriend Danielle Peazer last month, has been making the most his new single status too, at least according to Harry Styles.
During a recent radio interview where Liam was feeling under the weather, Harry said: "He's been kissing too many girls."
Wonder what rumoured new love Leona Lewis has to say about that...
