Ariana Grande just had the most hilariously terrible Japanese tattoo fail

Ariana Grande, queen of random tattoos, has been forced to face up to a huge, hilarious oversight after posting a photo of her latest ink on social media.

Grande opted for a Japanese tattoo on the palm of her hand to commemorate her latest single, '7 Rings' - seems like a fairly standard move for a global pop superstar, right?

Unfortunately, the design missed out some crucial kanji characters, meaning that instead of her hit track title, she's ended up with the term for a small Japanese barbecue indelibly inked on her body forever.

After showing off her new body art on social media, fans gleefully pointed out that the tattoo literally translates to "seven wheels," the term used for a traditional 'shichirin' charcoal grill.

If that's not pure poetry, I don't know what is.

The 'Thank U, Next' singer has since-deleted the Instagram post, because oh my God, of course she has, but she also fronted up to the mistake on Twitter.

"Indeed, I left out 'つの指' which should have gone in between," she said in a tweet she also deleted later, according to Vogue.

"It hurt like f**k n still looks tight. I wouldn't have lasted one more symbol lmao.

"But this spot also peels a ton and won't last so if I miss it enough I'll suffer thru the whole thing next time."

While Grande is likely to be reasonably shooketh following the blunder, it also appears she's maintained a sense of humour about it. 

"Also . . . [a] huge fan of tiny bbq grills," she added.

It's not the only time the 25-year-old has had tattoo regrets - she recently had to cover up several permanent tributes to ex-fiancé Pete Davidson following their break up earlier this year.

Some of her other ink includes a large illustration of her favourite Pokemon Eevee on her arm, and the letters "H2GKMO" on her hand, which stands for "honest to god, knock me out".

Could be time to step away from the tattoo gun for a hot second? Just a thought.
