Miley Cyrus Gets Matching Wave Tattoo With Liam Hemsworth's Sister-In-Law Elsa Pataky


Does this make them blood sisters-in-law?

Miley Cyrus keeps on riding the tattoo wave.

The "Wrecking Ball" singer got inked by one of her friends and longtime tattoo artists, Lauren Winzer, while in Australia on Saturday.

Cyrus' latest body art was a group effort, as she and three friends -- including Liam Hemsworth's sister-in-law, Elsa Pataky -- all got matching wave tattoos. The coolest part? The simple black line design was drawn up for them by pro surfer Kelly Slater.

Kalani Miller, one of the four ladies who got inked, re-grammed Winzer's photo and wrote, "When girls night starts out like this...Thank you @laurenwinzer for the new ink! And the boo @kellyslater for the scribble."

This wasn't even Cyrus' only new tattoo this week. Winzer drew Saturn on the inside of the 23-year-old singer's left arm four days ago, though Cyrus apparently either wanted Jupiter on her forever or just mixed up what the two planets looked like.

Winzer is also the one who gave her heavily tattooed pal an avocado tat last July.

The happy hippie has been spending a lot of time with Pataky since reconciling with Hemsworth. In fact, they had an all-female hang at the Soho House in West Hollywood, California, just last weekend.
