Miley Cyrus and Cody Simpson have cemented their romance by getting matching tattoos.

The couple went public with its romance in October, just two months after the Wrecking Ball hitmaker announced her separation from husband Liam Hemsworth.

Miley and Cody were spotted heading into a Los Angeles tattoo parlour during a night out early on in their relationship, and the artist who worked on the stars' designs, Nico Bassill, has now revealed the co-ordinated ink in a post on Instagram.

In one snap, Miley is seen displaying the outline of a trident symbol on her left wrist, while Cody has had a filled-in version added to his collection on his left upper arm.

"'Some mornings it's like the sun rises only for her.' Prince Neptune," Nico captioned the photo, seemingly referencing a poem the Australian singer/writer has penned about his girlfriend.

Cody is currently promoting his upcoming book, Prince Neptune: Poetry and Prose, which will be released on 7 April.

The 23-year-old has regularly been sharing snippets of the poetry collection on a dedicated Instagram page, and in one post, noted that he viewed the work as "like my notebook".

"It started when I was 18 living down in Venice Beach recording my poems, visions, thoughts. Now, at 23, it's filled, bound, published, and ready for you to get your hands on April 7. First copy arrived yesterday & I'm stoked," he gushed.

Meanwhile, Miley also recently visited Nico to get a replica of a Henri Matisse drawing on her right tricep.

No stranger to body art, the 27-year-old also has a number of mini designs on her hands, the word "freedom" tattooed on her right hand, and a snake motif on her left forearm.
