Miley Cyrus and Liam Hemsworth’s Sister-in-Law Elsa Pataky Get Matching Tattoos

Things are definitely serious.

Miley Cyrus and Liam Hemswroth’s sister-in-law, Elsa Pataky, got matching tattoos on Saturday (Apr. 30, 2016), pretty much solidifying her relationship with his family.

Australian tattoo artist Lauren Winzer posted a posted of their tattoos — a small, identical wave — on her Instagram page, writing, “Stoked to do these little matching custom waves @kellyslater drew up for @mileycyrus @kalanimiller @elsapatakyconfidential @aprilmun.”

Cyrus and Chris Hemsworth’s wife have been spending a lot of time together since she and the actor rekindled their romance. They not only spent time in Australian, but the couple even made a low-key appearance at the premiere of The Huntsman: Winter’s War.
