One Direction heartthrob Harry Styles is risking a whole host of infections by using DIY tattoo kits for his famous inkings.

The 'What Makes You Beautiful' singer has something of a passion for body art - and has already had a number of illustrations etched onto his skin.

However, it has been revealed that Styles has been letting a friend tattoo him with a home kit, which can lead to all types of infection including hepatitis and TB.

Kevin Paul, the professional tattooist Styles uses while in the UK, told The Sun that he's warned the 18-year-old star to stop using the dangerous DIY kits.

The artist - who also inks the likes of Ed Sheeran - revealed: “I tried to explain to him what the risks were but he doesn’t seem to care.”

One Direction are famed for their love of tattoos, with Zayn Malik and Louis Tomlinson inviting renowned tattooist John Bahel to their hotel room in New York City at the end of last year to update their inkings.

He said at the time: "They just gave me a buzz and I went down there. So [Zayn] was just super stoked on playing MSG and being in New York. He was just like super stoked that so many people came out, so many people came out from different areas of the world pretty much."

He added: "I'm pretty sure they don't want me talking about exactly what they got because that's on them. That's their personal thing, but I did not do 'MSG' on Louis."
