Producer Mike Will Made It has teased fans can expect a different sound on the 22-year-old star's fifth studio album, which the pair are making good progress on, describing her new music as "crazy".

He said: "We've got like eight or ten songs recorded, so we're just gonna pick the best songs to go on the album.

"It should be interesting though. Her whole sound is switching up, you know what I'm saying? It's crazy."

The 'Wrecking Ball' hitmaker recently revealed she has been working in solitude on the LP - which will be the follow-up to her 2013 album 'Bangerz' - with the 26-year-old musician sending her tracks to sing on.

She explained: "I don't have to have writers, I don't have to have f**kin' producers in there."

"Mike Will will text me a beat, and I'll go in my studio and work on it by myself."

Meanwhile, Mike - who produced her single 'We Can't Stop' and executive produced her whole 2013 record - is also working on his own album, on which he has enlisted the help of a variety of other stars.

He told MTV News: "It's a totally new sound from what I've been doing.

"I've been working with Fergie, John Legend, Schoolboy Q, Future, Snoop, all type of people on my album, No Doubt, all types of people."
