Miley Cyrus and Chris Hemsworth's wife get matching tattoos

Pop star Miley Cyrus and Chris Hemsworth's wife Elsa Pataky have got matching tattoos.

The Wrecking Ball singer reunited with Chris' younger brother Liam over Christmas (15), and the 23-year-old is clearly working hard to become part of the Hemsworth family once again.

While on vacation in the 26-year-old's native Australia, Miley and Chris' wife Elsa, 39, decided to cement their bond with identical body art.

The pair and two female friends opted for a small wave tattoo in black ink, with the finished result appearing on tattoo artist Lauren Winzer's Instagram account on Saturday (30Apr16).

"Stoked to do these little matching custom waves @kellyslater drew up for @mileycyrus @kalanimiller @elsapatakyconfidential @aprilmun," she wrote alongside the snap, which featured the four women's inkings on various parts of their bodies, including their wrists, a foot and a finger.

While it isn't clear which tattoo is Miley's or Elsa's, the body art trip is the latest outing for the star and member's of Liam's family.

Last month (Apr16), the couple was photographed in public together for the first time since it called off its engagement in September 2013 after three years of on-off dating.

Miley and Liam arrived for a family dinner at organic Mexican restaurant Gracias Madre in West Hollywood, along with Liam's other older brother Luke, his wife Samantha, and Chris, 32.

The pop star has been photographed wearing what appears to be her old engagement ring since the reunion, but the Hunger Games actor recently revealed to Australia's TV Week they are not planning to marry any time soon, saying: "I am not engaged, no."

Miley and Liam first met on the set of movie The Last Song in 2009.
