Miley Cyrus and The Flaming Lips planning nude

She is known for pushing the boundaries and he has some of the most extravagant stage sets around.

So the concept behind any show Miley Cyrus and Wayne Coyne were going to be involved in was going to be middle of the road.

The Flaming Lips singer took to Instagram on Tuesday to reveal he and the blonde haired singer are going to be performing together in concert…naked.

And not only that, the singer is planning the audience are sprayed with a white substance that looks like milk.

Frontman Wayne captioned a picture of himself with The Flaming Lips, sans clothes: ‘Oh f**k..!!!’ he eloquently opened, minus the asterisks.

‘@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,’ he wrote.

‘It’s a video ( in the works) for #mileycyrusandherdeadpetz song The Milky Milky Milk.’

Milky Milky Milk is indeed a song on Mileys new free album, song number ten of 23 that include such timeless gems as Bang Me Box, Slab Of Butter, Pablo The Blowfish, and of course, I’m So Drunk.

Miley herself was uncharacteristically quiet on the matter on her own Instagram account.

However the 22-year-old did confirm earlier this month that she will be touring with the band.

Miley and Wayne have collaborated on a number of songs before, and even starred together in the hilariously trippy music video for Blonde SuperFreak Steals the Magic Brain.

The twosome – as well as Coyne’s girlfriend Katy Weaver – even recently got matching tattoos of Cyrus’s late dog, Floyd.

And it’s certainly not the singer’s first encounter with milk.

Back in her Hannah Montana days, the then-teen and now-almost unrecognizable star lent her face to the Got Milk campaign, in what was at the time considered a controversial picture.

On Monday, Miley courted controversy  once again when she posted a picture of herself smoking a bong, with the caption: ‘Dessert is served mi lady’.
