At just 18 years old the mop haired heartthrob has already littered his body with a number of carefully thought out etchings.
Pleased with his growing collection, the Live While We're Young singer was happy to show off a bit of flesh in the revealing snap posted by a Directioner on Twitter.
Among his inkings are a black star, an Iced Gem, comedy and tragedy drama masks and a birdcage.
Although it is not clear when this particular picture was taken, Harry was spotted heading to a tattoo parlour in west Hollywood earlier this month where he reportedly got his elder sister Gemma's name tattooed in Hebrew on his upper left arm.
He's also got '17 black' tattooed on his collar bone, the letter 'A' in the crook of his elbow and Temper Trap lyrics 'won't stop 'till we surrender' also on his arm.
Fellow musician Ed Sheeran recently etched a little locket on Harry's hand.
