Entertainment Tonight

Britney Spears' new revealing documentary "Britney: For The Record," debuted Sunday night on MTV, but the pop-princess opens up even more in the January issue of Glamour magazine. Britney dishes on her family life, her new album, and what she hopes to change in the new year.

In the issue on stands Dec. 9, Britney opens up about making positive changes in her life -- and what role her new album played in turning things around.

"Recording this album has helped take my mind off certain things," Britney says. "For me, my music is therapy."

The mother of two also talks about getting back in shape and shedding the pounds she gained during her pregnancies.

"I'm getting there," Britney says. "Recently I started to appreciate my body a bit more from before I had kids. My body...completely changed [after giving birth], and I have had to work hard at getting it back."

Britney goes on to describe how she enjoys spending her free time.

"I don't like going out," she says. "I hate clubs. I hate being around too many people. I love my home and staying in bed and watching 'Dancing With The Stars' or reading a Danielle Steel novel. I'm kind of boring."

Besides re-establishing herself as a pop powerhouse, Britney says she has other aspirations for 2009.

"I would like to stop worrying so much because I worry all the time," she tells the mag. "And to learn how to be happier, just in general. I have to learn to take things not so seriously."
