As if she needed more ink!

Miley Cyrus headed to Unbreakable tattoo parlor in Studio City for some fresh skin art on Sunday with her assistant, and the besties got their pet names BIEWTY on their arms. We're not a big fan of tats, and the songstress is starting to look trashier by the day!

The twerking queen doesn't exactly have the most squeaky clean image, so it's slightly confusing that she's been hanging out with Tallulah Willis lately. Bruce and Demi's daughter went to rehab this past summer, and a person focused on their sobriety probably shouldn't be spending time with the weed smoking "Wrecking Ball" hit maker.

They Instagrammed an innocent pic of them playing Twister, but we doubt all their activities are so PG!
