No Promises Cheat Codes feat. Demi Lovato
The N-Dubz star gets a new set of gnashers for the show.
Tulisa Contostavlos has undergone dental surgery to sort a perfect set of teeth in time for the launch of The X Factor.
"Since she became famous she has become aware they are not perfectly aligned," a source spilled.
"So she decided to pay for a bit of help.
"It didn't come cheap but she's determined she will look the part."
Tulisa has been undergoing surgery for the "last couple of weeks" according to The Sun so she can look her best for the judges' boot camp stage.
The UK series of The X Factor will start on Saturday 20th August.
