The lad has gone and had the words 'The' inked on one shin and 'Rogue' on the other in tribute to the band he was in before finding fame with One Direction. Oh dear.
Louis' new tattoo
Louis' girlfriend Eleanor Calder uploaded a snap of him showing off his new tat on Instagram, where his trademark sockless ankles were also on show.
Before Louis was a global megastar, he used to play with the band in school assemblies and wrote on his old Bebo account that their favourite songs to perform were 'Hey There Delilah' and 'I'm A Believer' by The Monkeys.

But his new tribute tat isn't his only fresh ink, as he looks to have had a massive new one done across his chest.
In another photo uploaded by Eleanor, the inking was visible as Louis played guitar in a vest.
