Pop princess Britney Spears confessed she's mad about sex, especially since she got pregnant. The singer told America's People magazine: "I think it's best. Sex is crazy good."

Britney also confessed that the first scan of her baby left her speechless: "You can't really say anything... I think it's the best feeling in the world."

She added: "I'm sure there's going to come a time when I get back to work again, but it'll be a totally different way of life than it was before."

A few days ago, Britney Spears announced she decided to film her birth for the next series of her reality TV show Britney&Kevin: Chaotic.

Britney, who expects a child this fall, will show the footage in a one-off sequel to her hit reality series 'Britney and Kevin: Chaotic'. The baby will be Spears' first child and husband Kevin Federline's third.
