N-Dubz keep American adventure a secret

N-Dubz are keeping their American dream underwraps, simply saying they are "in negotiations".

Rumours have been rife about the grime trio's plans to conquer the US. There was even speculation the band were already starting househunting.

"There's nothing confirmed yet," singer Tulisa said.

She added: "We're not really allowed to say much about it.

"We're just in talks about a record deal, and that's how we shall leave it."

The group have made no secret of their dreams to crack America like fellow Brits Estelle and Jay Sean and it is thought they could sign with US label Def Jam after impressing boss LA Reid.
