Britney Spears is opening up in E! documentary I Am Britney Jean.
The 90-minute special airs Dec. 22 at 9 p.m., five days before the 32-year-old pop singer unveils her two-year residency, Britney: Piece of Me, at Las Vegas' Planet Hollywood. I Am Britney Jean will offer "an intimate look at one of the most overexposed yet under-revealed stars of today as she faces one of her biggest challenges ever while finishing her album, shooting videos, doing press -- and being a mom," according to E!.
In clips released Thursday morning, Spears -- a mother of two young boys -- is seen discussing sex and how her perspective on it has changed over the years.

"I love sex. I think sex is great, but I feel a little different about it not that I'm older," she admits. "Sometimes I feel like I'm 20 and then sometimes I feel like I'm 50."
In another clip, Spears is seen working out new choreography to one of her old hits, "Toxic," with co-choreographer Antony Ginandjar 112 days before the Las Vegas show opens.
"This year I have new choreographers. They're new, up-and-coming, fresh guys so their stuff is really hard," Spears says, adding that it's "rewarding" after doing something that's difficult.
