Miley Cyrus lifts the lid on her life and addresses her critics in a revealing trailer for 'Miley: The Movement'.

During the documentary - which is set to air on MTV on Wednesday (02.10.13) - the 'We Can't Stop' singer discusses her plight in redefining her career and image following the end of her Disney show 'Hannah Montana' and the lead up to the release of her fourth studio album 'Bangerz'.

She muses: ''I was born to become who I am right now ... I'm at a point in my career where I can be exactly what I want to be, who I want to be.''

''I have this freedom to do whatever I want, because I'm starting as a new artist now,''

''Every time I do anything, I want to remember, this is what separates me from everybody else.''

Miley also addresses the backlash surrounding her controversial performance at the MTV Video Music Awards performance last month and insisted she is not one to shy away from controversy.

She explained: ''You're always going to make people talk, you might as well make them talk for two weeks, rather than two seconds.''

The 20-year-old star admits she was ''nervous'' backstage at the ceremony moments before she stripped down to a latex bikini to sing and twerk with Robin Thicke on 'Blurred Lines', as she is heard saying: ''I am more nervous than a mother-f***er, I'm not gonna lie.''

In a series of intimate moments the star is also seen chatting in the studio with Britney Spears - who collaborates on 'Bangerz' track 'SMS' - as well as joking with her album producer and rumoured love interest Mike WiLL Made It.
