Flaming Lips headmaster Wayne Coyne has been talking about working with smoking buddy Miley Cyrus for a while, but he's been frustratingly opaque about it. But now we know what to expect ... sort of.

Coyne spoke with Billboard recently, giving the run-down on what the Lips and Cyrus have in store for the music-loving populace. He also talked a bit about what working with her has been like.

"Her studio is just a little room with a desk," he said. "And Miley was sitting there mixing. I was like, 'I can't picture Beyoncé doing this!' It's not a ­putdown of Beyoncé. I just don't see her recording her own vocals and then EQ'ing it. It's so punk rock!"

Coyne said that they don't have a release date yet, but all the recording is done, and they're mixing the album now. The album will be seven songs long, and the way Coyne describes it, it definitely sounds interesting.

"She does the pop thing so great, so it still feels pop, but a slightly wiser, sadder, more true version," Coyne explained. "Some of it reminds me of Pink Floyd and Portishead."

This new project isn't the first time we've heard this unlikely combo. Cyrus popped up a few times on the Lips' tribute to the BeatlesWith a Little Help From My Fwends. This will, however, mark the first time they've worked on original material together.

We wait with baited breath.
