X Factor mentor and former NDubz member Tulisa Contostavlos has split from her long term boyfriend and band mate Fazer.

The pair are believe to have called it a day after a series of blazing rows have caused them to grow apart, that coupled with the fact that Tulisa’s profile is soaring since her appearance as a mentor on the hit reality show and her schedule is filling up with endless commitments , a source told UK tabloid The Daily Mirror, “It’s all over for Tulisa and Fazer. Fazer has been out clubbing twice this week without Tulisa, and she, too, has been spending more time with her friends away from him. They are insisting nobody else is involved and clearly don’t want to stick the knife in to each other because they’ve been close since they were 11.” They continued, ”They’ve still got a lot of respect for each other, but they’ve had a very turbulent relationship.”

The Greek beauty has allegedly moved out of the couples North London pad and moved in with her PA Gareth Varey until things settle down and she can move on.
