During some kind of impromptu-looking let's-get-inked party, the "Adore You" singer and Flaming Lips frontman decided to pay permanent respect to the Lips' epic 2002 album-turned-musical, Yoshimi Battles The Pink Robots.

Miley showed off the mini-robot tattoo in a photo she took with Coyne and his girlfriend, Katy Weaver.
Miley captioned: "bestie yoshi tatz."
For reference, here's the Yoshimi album cover:
Wayne also got a Miley-branded smiley face on his right foot.
Miley's been on a bit of a tattoo tear lately.
