Pop mom Britney Spears is back on track and she's opening up about her unusual behavior in a new documentary for MTV. "For the Record" combines personal stories with behind-the scenes footage of her comeback.
The pop star confessed that she is confused about the past few years, "I sit there and I'll look back and I'm like, I'm a smart person. What the hell was I thinking?"
In the film's sneak peak, Brit reveals, "I've been through a lot in the past two or three years, and there's a lot that people don't know." It is known that the Britney train is rolling. The video for her single "Womanizer" premieres tonight on ABC.
