Miley Cyrus has debuted some new ink, despite admitting she regrets most of her 50-plus tattoos.

On Monday, the Grammy-winning singer's tattoo artist shared close-ups of her latest work - a small tattoo reading 'Muse' on Cyrus' back, just below her right shoulder.

"Queen @mileycyrus - grateful to have met such a G," the artist captioned the carousel.

Fans speculated that Cyrus' latest tattoo may be a sweet homage to her mother, Tish Cyrus.

In April, the Flowers hitmaker took to Instagram to share her private performance of End Of The World at Los Angeles' Chateau Marmont last year, shouting out her mum in the caption.

"The secret of a song before it's released is such a sacred time," Cyrus wrote.

"I am honoured today to have it out in the world hopefully bringing some joy, but on this night I was singing only to the person I wrote it for. My muse, my mom."

This latest artwork may be a meaningful design but that's clearly not the case for much of her previous ink.

When asked in a video interview for The New York Times just one day prior what one mistake she's made that she still thinks about, Cyrus answered bluntly, "Eighty per cent of my tattoos."
