Britney Spears will candidly discuss her troubled year for the first time in a new MTV documentary.
The 90-minute film, tentatively titled "For the Record," sees the 26-year-old star discuss her public meltdown ahead of the release of her new album Circus.
Britney said: "So much has gone on over the last couple of years and there's a lot that people don't know about me that I want them to know."
"I wanted to make this film because I started to feel like I wasn't being seen in the light that I wanted to be seen in. This is an opportunity to set the record straight and talk about what I've been through and where I'm headed."
In a clip from the documentary, set to air on MTV in America at 10 p.m. on November 30 - two days before the release of Circus - Britney is seen pondering her past.
She says: "I sit there and I'll look back and I'm like, 'I'm a smart person. What the hell was I thinking?' I've been through a lot in the past two or three years, and there's a lot that people don't know."
"Sometimes I think I get kind of lonely because you don't open the gate up that much, you know I mean? You're guarded. You have to be that way, so I'm kind of stuck in this place and it's like, 'How do you deal?' And you just cope, and that's what I do. I just cope with it, every day."
This is not the first time Britney has appeared in a documentary.
She also starred in "Britney and Kevin: Chaotic" alongside ex-husband Kevin Federline in 2005.
