He's already amassed a sizeable collection of body art since shooting to fame in One Direction two years ago.
But it would seem Harry Styles' penchant for tattoos is far from over, as he sported a brand new inking on Tuesday night.
The 18-year-old singer, accompanied by his doting girlfriend Taylor Swift, 23, made the Shamrock Tattoo Parlour his first port of call when he jetted into Los Angeles, California, with his One Direction bandmates.
And the star certainly didn't opt for a subtle addition to his collection of etchings, having a large ship design decorate almost all of his upper arm.
Looking a little red and sore, the new tattoo sat next to the large heart Harry already has on his bicep.
In spite of the pain associated with the inking, Harry beamed away as he posed for a photograph with his tattoo artist at Shamrock, which is also a favourite haunt of footballer David Beckham.
Taylor made sure she was close by to hold Harry's hand through the procedure, with the singer chatting to a female pal as her boyband beau went under the needle.
The I Knew You Were Trouble hitmaker appeared to have embraced her grungy new surroundings, taking part in a game of pool with her friend as Harry underwent his newest inking.
Looking stylish in a monochrome swallow-print dress and a slick of red lipstick, the country music star beamed as she posed alongside the One Direction hunk for a series of photos.
But it would seem she wasn't keen to alter her clean-cut image with a tattoo for herself.
Harry has been a big fan of body art for some time, most recently showing off a large pair of birds on his chest, which was etched at Shamrock last month.
On either forearm, the star has the unfinished phrases 'Things I can' and 'Thing's I can't', as well as a series of seemingly random images, including a small padlock - tattooed on by his singer pal Ed Sheeran - two zig zags, a skeleton of a fish and the figure 99p.
The teen idol also has a large star on his inner arm, and recently added the song lyrics 'won't stop 'till we surrender' from The Temper Trap track Sweet Disposition beneath it.
Additionally, Harry currently has a tiny 'A' in the crook of his elbow, which is believed to be a tribute to his mother, Anne Cox, who he is extremely close to, as well as '17 black' etched on his collar bone, an Iced Gem, comedy and tragedy drama masks, a birdcage and the words SMCL.
The words SMCL have led some fans to speculate it means 'smile more, cry later' or 'Simon Cowell' - who famously put the band together on X Factor two years ago.
Meanwhile, Harry and his bandmates Liam Payne, Louis Tomlinson and Zayn Malik all have matching screws inked on their ankles, and have been urging Niall Horan to complete the set.
Harry recently wrote on his Twitter page: '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.'
The star was previously believed to be planning on opting for a full sleeve to add to his collection of 'personal' etchings.
Celebrity tattooist Kevin Paul recently said: 'Last time I spoke to Harry he said he is going to hold off on the sleeve for now but will be getting new bits soon.
'They’re really personal to him - the reasons he had them done and stuff, so he doesn’t really want to announce what they are. One was something from his childhood, and another one was something really important in his life.'
The One Direction boys arrived at Los Angeles' LAX Airport on Tuesday morning, but it is not clear why they have returned to the US so near to Christmas.
