Pregnant pop princess Britney Spears is following her husband Kevin Federlines lead and learning to rap for her new "edgy" album.

The 'Toxic' hit maker has enlisted Destiny's Child producer Jonathan 'Jr''Rotem to help cultivate her new sound.

The 24-year-old, who announced her second pregnancy on 'The Late Show With David Letterman', last week, has vowed to balance her growing family with her pop career.

Rotem tells MTV, "She's been a mother and she'll still be doing that, but she's very much into her music. She literally can't go anywhere without her privacy being invaded. Everybody is trying to get information. So the record we wrote, it addresses the 'who do you trust' kind of thing. Not rap rap, but talk rap.

It's definitely Britney, but the next level. With songs like 'Toxic' she was very innovative, and we're trying to top it. Push it to the next thing. The album wouldn't come out in a while anyhow, since it's at the very beginning. When it comes time to promote the album, she'll be in a different headspace where that's going to be the main thing. But right now, she's happy juggling music and motherhood." (wenn)
