Further details of Miley Cyrus's collaborative album with The Flaming Lips have emerged.

The pop star - who is hosting the VMAs this coming Sunday - has worked with Wayne Coyne and co. in the past, initially on the latter's 'With a Little Help from My Fwends' covers album last year.

It was reported several months back that a full-length album is on the way too, with Cyrus teasing a song called 'Tiger Dreams' back in May and Coyne describing the sound as "Portishead and Pink Floyd", saying that they'd written and recorded seven songs together.

Now, a source has told Billboard that the new record is "not a typical, straightforward Miley record." 

"It’s amazing, it’s incredible, it just needs to be understood that it’s not a typical, straightforward Miley record," they said. "We don’t want there to be confusion in the marketplace.”

Cyrus's last album was 2013's 'Bangerz', but her next one will be "somewhat psychedelic rock," according to the source. "But Miley’s writing sensibilities lean toward pop, so it’s a nice, healthy mix of both. But at the end of the day, it is Miley."

"She’s super-excited about it," they added. "The Flaming Lips are her favorite band and she’s wanted to work with them her entire life. I think people are really going to be surprised.”
