X Factor 2011: Tulisa warns Nu Vibe to up their game or face axe

Harsh new X Factor judge Tulisa has warned Nu Vibe to work harder, of they face the axe. Having saved the boys over 2 Shoes on Sunday night during the shock twist, Tulisa reportedly summoned the group to her dressing room for a stern talking too.

It's fair to say the boys disappointed on Saturday night, with a far from brilliant vocal performance of Chris Brown's Beautiful People.

An insider told The Sun that Tulisa made it clear to the group that they had to up their game to stay in the show.

"She said they had to knuckle down and work harder or they would be voted off the show — and soon," the source said. "She said even though they showed promise they had not put enough work in and she expected more from them."

We'd be very surprised if they're not in the bottom two this weekend...
