If you need further proof that Miley Cyrus and Wayne Coyne are literal, real-life BBFs, well now they've gotten another set of matching tattoos to prove it.
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.
Oh hi, pink robot.
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.
Earlier this month, the singer freshened up and added to her finger tats while in Australia, and added a Flaming Lips tribute to "Love Yer Brain" on her forearm back in August.
