Miley Cyrus believes her upcoming MTV documentary will be an "insane" ride.

The singer is due to star in Miley: The Movement, a one-hour look into the life of the 'We Can't Stop' star.

Speaking to MTV, Cyrus whetted fans' appetites by revealing that the programme will showcase both the highs and lows of her existence. She said:

"I want all my fans to come with me; to the studio, on the road, at performances. There's going to be a lot of ups and downs, and it's going to be completely insane. You've gotta be a part of the movement with me."

The documentary is due to premiere in the US on October 2.

Cyrus meanwhile recently broke the VEVO 24-hour views record with her revealing new promo clip 'Wrecking Ball', which can be seen below.
