Songstress Miley Cyrus recently debuted the music video for her new single 'Wrecking Ball' and the track's songwriter has now hit out at the criticism it has received as a result of the star's nudity in it.

MoZella, whose real name is Maureen Anne McDonald, co-wrote the song and took to her official Twitter page last night to defend Cyrus and the artistic direction she took with the bold video: "I'm just going to throw it out there. Maybe nudity is the representation of feeling emotionally stripped & vulnerable. And maybe she is kissing the sledgehammer because we all secretly love the pain."

Meanwhile, MTV are set to unveil a documentary about Cyrus later this autumn called 'Miley: The Movement' and it will debut on October 2, just before her new album 'Bangerz' is released on October 7.

Speaking about the documentary, Cyrus explained: "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."
