Former Disney superstar Miley Cyrus has been hard at work on a new album and teamed up with production duo Da Interz for the new cut.

Marcos 'Kosine On Da Beat' Palacios, of Da Internz (pictured below), explained to MTV News that they were impressed with her sassiness and were surprised at how "different" she was in person to their initial expectations:

"Yo, first of all, Miley is nothing what we expected. We expected her to be super reserved and so we were trying to be [that way too]. You know what I mean? She came in like, 'What up? What y'all doing?' We like, 'Oh, how you doing?' We had a good time! Miley is turned up!"

His production partner Ernest 'Tuo' Clark added: "You got to think about this, never met Miley Cyrus and she invites us over to her house and first time meeting her saying 'hi' is singing Big Sean's 'Dance, Dance, Dance', the Nicki Minaj verse."

"She sang the explicit version. We was like, we was looking at her and she's like, 'Hey! That's my song, nice to meet you'. We was like, 'Oh man, nice to meet you'. It was different for us. But the project and the direction she's going, she's still staying to the roots but it's just she's grown now. She's grown now and she's exploring different things and it's definitely a new sound, it's not nothing that's mocked."

When asked about their impression of the 'Can't Be Tamed' beauty after spending time with her, they agreed: "She's not trying to be like another actress out here. She's just having fun on her records. She's, like, full of energy and just having fun right now."
