With speculation that Mel B is being lined up to replace Tulisa on X Factor in 2013, the 'Sight Of You' singer is already poised to quit the show to return to N-Dubz.

The singer's plans have been revealed by her father, who has given an interview to Now magazine, spilling Tulisa's plans to leave the show and adding that she only ever did it for the cash.

"Tulisa doesn't want to be there. She's bored of it. She doesn't need The X Factor, she's got N-Dubz," Plato Constavlos tells the celebrity magazine.

"I want her to leave X Factor. N-Dubz can do one gig and earn up to £500,000. I want her to make some serious dosh, millions, by doing an independent album with N-Dubz.

"What I want for her is security, so she never has to rely on anybody apart from herself."

Tulisa's place on the show is in jeopardy after her debut album and December single 'Sight Of You' flopped - despite spending two years in a prime time TV spot.

Mel B has been widely named as a judge for X Factor 2013

Tabloid sources have revealed that Mel B is set to return to the UK after finishing her role on X Factor Australia to take a place on the 2013 judging panel. The 'Wannabe' star has been a judge on X Factor in Australia and is now set to return to the UK for a permanent role, reports weekend tabloids.

"She’s ready to come back. All her obligations in Australia, where she’s been living for two years, come to completion at the end of January," says a source to The Mirror.

"Phoenix [her daughter] really wants to be in the UK and Mel’s getting signs that things are going to work out with The X Factor.

"The thing about Mel is she goes where she’s wanted and where the work is. And if that’s the UK then so be it."
