The much-anticipated Britney Spears documentary called Britney: For The Record, isn’t airing until November 30 on MTV, but plenty of juicy clips have already surfaced on the Internet. The singer, who’s had a rough couple of years, draws comparisons to her life and a jail sentence. “Even when you go to jail ... there’s the time when you’re gonna get out. But in this situation, it’s never-ending. It’s just like Groundhog Day,” says Britney. Of being hospitalized for a mental evaluation in January, losing custody of her sons and having her father, Jamie, take control of her affairs, Britney notes, “I have really good days, and then I have bad days. I’m having to pay for it for a really long time.” But the singer, who’s poised for a major comeback, sounds optimistic about the future. “I think I’ve learned my lesson now, and enough is enough.”
