N-Dubz would pose naked for "a fiver".

The only female member of the group, Tulisa Contostavlos believes it would only take a small sum of money for her bandmates Dappy and Fazer to happily bare all for their fans.

When the group were asked how much it would cost for them to pose nude, Tulisa replied: "For these two? Give them a tenner; a fiver even."

Dappy added: "If our careers finished, then yeah, I'd pump up quickly get some protein shakes, let it dangle, and just take a picture."

While Tulisa thinks her bandmates have no problems with baring all, she insists she would never Expose her flesh in exchange for money.

She exclusively told BANG Showbiz: "I'm priceless, you couldn't put a price on me. I'd never strip, that's my number one moral."

Rapper Dappy - real name Dino Contostavlos - added that he's comfortable with his slimline frame and doesn't have plans to start working out for when the band start to promote their new album in the US, though he thinks he would fit in better Stateside if he bulked up.

He said: "In the video for our single 'Best Behaviour' maybe we'd just done a few press ups before the shoot, but I like it kind of slim and normal. But I could be maybe a bit more cut, a bit more meat... slightly.

"Everyone's bigger In America - bigger, smellier, crazy out there, it's much more. Everyone's bigger - when you're fat you're fat. Even the skinny people have still got meat on them."

'Best Behaviour' is available now, while N-Dubz as-yet-untitled album will be released on November 19.
