London, Oct 27 (IANS): Singer Tulisa Contostavlos reportedly wants to bring together her N-Dubz band once again but other two members Fazer and Dappy have rejected the idea.

Contostavlos, 24, is currently seen as judge on reality show "The X Factor" and knows she will be a bigger name with the band coming together rather than struggling with a solo career.

"Tulisa thinks N-Dubz would be bigger than ever following her exposure on 'The X Factor' but her old band mates just aren't interested. Dappy and Fazer want to continue doing their own thing," dailymail.co.uk quoted a source as saying.

"They know Tulisa's solo career isn't going great and she's realised she's bigger as part of N-Dubz than on her own. Her record company are nervous after her last single and fear it could be over for her after one album," the source added.

The singer's last song was "Live it up" which failed to impress music lovers. Her upcoming album is "Female Boss".
