It seemed like Tulisa Contostavlos had her love life all sorted in recent months, as she was frequently pictured looking all loved up with her N-Dubz bandmate Fazer, but insiders say that the couple have now decided to split.

The X Factor judge was describing the rapper and music producer as the ‘best boyfriend ever‘ just a few short months ago and describing how loved up and happy they were together, however the couple have now reportedly decided to call time on their relationship and have went their separate ways.

The split is said to have came about because the brunette beauty was getting tired of Fazer’s constant partying and hitting the town and his behaviour and social calendar led to a series of rows between the pair.

The had been dating for eighteen months, but friends told The Mirror that after spending less and less time in each other’s company, Tulisa and Fazer have decided to break up.

A source said: “It’s all over for Tulisa and Fazer.

“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’ve still got a lot of respect for each other, but they’ve had a very turbulent relationship.”

The couple have split before and people close to the pair claim that it is not uncommon for them to argue and talk about breaking up, however some seem to think this time it may be for good.

An insider added:

“One of them will often storm out and tell the other their relationship is over during their fiery rows.

“But they really do sound serious this time. It wouldn’t be out of the ordinary if they changed their mind in a week or two and got back together but their closest friends feel it’s different this time.”

Tulisa and Fazer dated secretly for almost a year, before confirming their relationship in 2011. They sparked engagement rumours just a few short months ago and even Contostavlos’ dad told newspapers that his daughter was ‘in love’ with her bandmate.

Fazer was hoping to work on X Factor winners Little Mix’s debut album.…we wonder if that will still go ahead now?
