In a new clip from Britney Spears'Britney Spears' forthcoming documentary, "For the Record," that has made its way online, the singer opens up about her two-year marriage to Kevin Federline, and how in retrospect it probably wasn't the best decision she could have made at the time.
"I think I married for all the wrong reasons," she says in the 90-minute documentary, set to air on MTV on November 30, just two days before the release of her new LP, Circus. "Instead of following my heart and, like, doing something that made me really happy. I just did it because ... for just, like, the idea of everything."
In the clip she also talks about what the album means for her, after several tumultuous years in the spotlight. "It's weird because your music is a reflection of what you're going through," she says. "It's such a part of me, the record, 'cause of what I've gone through."
In another clip, Spears talks about how she uses her work as a dancer and singer to deal with the stress of her life and how it helps her deal with her emotions. She said that for her, dancing is like therapy. "If I have a lot of nervous energy, when I start dancing it all goes away and I just feel emotion. It's like a rollercoaster," she says. "People think that when you go through something in life you have to go to therapy. For me, art is therapy, because it's like you're expressing yourself in such a spiritual way.
"Sometimes you don't need to use words to go through what you need to go through," she continues. "Sometimes it's an emotion you need to feel when you dance, that you need to touch. And the only thing that can touch it is when you move a certain way."
In previously released clips, Spears addresses her reasons for making the special now. "There's a lot people don't know about me that I want them to know. ... I've been through a lot in the last two or three years. I've grown up, bigtime," she says.
She also talks about being a public figure and having every moment of her life documented by the media. "I don't think anyone can prepare themselves for what stardom brings," she says, adding, "Do I know my life is weird? It's all I've ever known."
