Want to know what was going through Britney Spears' head during her darkest days? Tune in to MTV's 90-minute exclusive documentary "Britney: For the Record" to find out.

Airing Nov. 30, "For the Record" documents a three-month period of Spears' life earlier this year, including sessions for her upcoming Jive album, "Circus," and preparations for her appearance on MTV's Video Music Awards.

An MTV spokesperson says "no topic was off limits" during the interviews.

"I sit there and I look back and I'm like, 'I'm a smart person. What the hell was I thinking?,'" Spears says at one point. "I've been through a lot in the past two or three years and there's a lot that people don't know."

"Circus" is due Dec. 2 via Jive. First single "Womanizer" debuted this week at No. 26 on the Mainstream Top 40 chart, No. 96 on the Billboard Hot 100 and moved 44-32 on the Pop 100 in its second week on the chart. It should rise substantially on the Hot 100 next week, after its first round of digital sales are factored in.

The "Womanizer" video premieres tomorrow (Oct. 10) on ABC's "20/20."
