Miley Cyrus just wants to have fun and not think about the "repercussions."

"Right now I'm at a point in my career where I can just be exactly who I want to be," the controversial pop star said in a new one-hour documentary, " Miley: The Movement," premiering on MTV Oct. 2. "I can just have fun and not think about any kind of repercussion and just go for what you want to do. That causes a lot of reaction but I think there's something about watching people grow up."

The 20-year-old former "Hannah Montana" star knows all about causing a reaction. In the documentary, she discusses her infamous performance at the Video Music Awards, her much talked-about haircut and her decision to never appear in another movie.

Britney Spears, Cyrus' collaborator on her upcoming single "SMS (Bangerz)," even makes an appearance in the film.

"With the VMAs coming up, what you did with Madonna is when you blew up and that's what I'm looking at," Cyrus told Spears in the special. "That's what you've kind of been for my generation. For me that's when I got into music. I want to give people that again, just videos that are out of control and people can't believe the performances."

"You're not going to be topless on stage?" Spears responded.

"I tried to go there but I don't think MTV's going to allow it," Cyrus replied.

By now, everyone knows that Cyrus twerked her way to infamy.

After the performance, she told the documentary's director, "I don't pay attention to the negative because how many times have we seen this play out in pop music? Madonna's done it, Britney has done it, anyone that's performed on the VMAs, you know? You're always going to make people talk. You might as well make them talk for like two weeks rather than two seconds. I've been laughing about all the news because everyone else is so serious.

"Everyone's worked up and frazzled and I'm chilling," she added. "I'm like, 'I forgot about that performance it's so behind now. On to the next performance.'

"Yes, I am very comfortable with sexuality, I like pushing the boundaries, but I'm coming out in pigtails looking like a giant adult baby basically. That's obviously funny. If I really wanted to put on a sexy show I wouldn't have been dressed as a damn bear," she said.

About the haircut that changed her life, she said: "I told my hairstylist, shave my head, dye me blonde. I need to let go of like a past in a way because I felt like we need to see change. I felt like I had this whole new attitude. I felt like I could finally be the bad b***h I really am. Even the way I dress has opened up."

But don't look for Cyrus on the big screen anytime soon.

"I made one movie, and I never wanted to do it again," Cyrus said, referring to her little-seen 2012 film "LOL." "I want to make music for the rest of my life."
