N-Dubz Write Song About Teenage Pregnancy

N-Dubz are hoping to prevent teen pregnancies by releasing a song about the subject on their second album.

'Who Do You Think You Are' is a track about a teenage couple who have fallen pregnant, and follows their arguments over whether to keep the baby or not.

"It's not something any of us have been through personally," singer Tulisa told the Daily Star. "But everyone knows someone who has."

And N-Dubz took their time writing about the serious matter, each trying to put themselves in the mind of someone in that position.

"The three of us wrote down our different perspectives," Tulisa continued. "And we based the song around that. It's our favourite track on the album."

N-Dubz release the follow-up to 'Uncle B' later this year.
