Miley Cyrus just got matching tattoos with a special someone. That's quite a commitment.

We have all been wondering for weeks now if Miley Cyrus and Liam Hemsworth are back on again.

In the latest chapter of pretty certain evidence that the pair are back on, Cyrus and Chris Hemsworth‘s wife Elsa Pataky have made a trip to the tattoo parlour together.

Cyrus and Pataky both got small, delicate tattoos of a wave. Cyrus’ ink appears to be on her foot, whereas Pataky’s new tattoo is on the inside of her finger.

Hmm, surely you would only get matching tattoos with a really close friend? Someone you see as a sister. Or, a future sister-in-law, perhaps?

Cyrus and Pataky’s tattooist Lauren Winzer, who also gave Cyrus her recent Jupiter tattoo, shared a photo of the ladies and their new ink on Instagram. Their friends Kalani Miller and April Mun also joined in on the fun.

Winzer also revealed that American surfer Kelly Slater designed the tattoo.

Elsa Pataky and Miley Cyrus were also seen together in a photo from a girls’ lunch a few weeks ago.
