Miley Cyrus donned a prosthetic penis on stage as she kicked off her Dead Petz club gigs in Chicago on Thursday (19.11.15).
The controversial former Disney star hit the stage at The Riviera Theatre in a number of racy outfits, including one featuring metallic bondage-style underwear and matching thigh-high boots, with fake boobs and a penis.
The concert was the first of a six-date tour which Miley is embarking on with her latest album, 'Miley Cyrus & Her Dead Petz'.
Miley's tour - also featuring The Flaming Lips - will visit Detroit, Washington, New York and Philadelphia, before a final show in Boston on December 6.
Flaming Lips frontman Wayne Coyne previously revealed plans for Miley and the band to take to the stage without any clothes on, while the audience - who will also be asked to strip - are sprayed with a white substance that "looks like milk".
In an Instagram post - featuring a naked split-shot of the band and Miley - Wayne wrote: "Oh f**k..!!! @mileycyrus is planning a show where her, the band ( us ) and the audience are all COMPLETELY naked with milk ( well white stuff that looks like milk) is being being spewed everywhere .. It's a video ( in the works) for #mileycyrusandherdeadpetz song The Milky Milky Milk... (sic)"
Meanwhile, Miley, 22, recently spoken of her "love" for the band's 54-year-old lead singer.
The 'Wrecking Ball' hitmaker said: "He's everything in the world - you can't even define us.
"I am 100 percent in love with Wayne, and Wayne is in love with me, but it's nothing sexual in any way. That would be the grossest."
