Rumours that babies and weddings scared her off
Despite N-Dubz bandmates Tulisa Contostavlos and Fazer splitting a few weeks ago, there has been little news of the reasons behind the split.
It seems, however, Tulisa may no longer have trusted Fazer, and felt trapped by his 'marry me or lose me' ultimatum.
Closer magazine reports that the X Factor judge had become increasingly concerned about her boyfriend's friendship with Made In Chelsea star Chloe Green. It is alleged that she texted him throughout the couple's romantic holiday in the Maldives.
The source says that it led it to a fiery showdown with Fazer stating: "I want marriage and a baby and it seems all you want is fame!"
The mole added: "He told her if she wasn't prepared to commit to starting a family, she couldn't tell him who he could or couldn't speak to."
Heat magazine also claims that Fazer wanted Tulisa to leave the X Factor and commit to the relationship instead.
They said: "He told her that he thinks she should quit the X Factor, and that she'd changed. It really cut through Tulisa and she started to cry."
Unusually for celeb couples, Tulisa and Fazer have not spoken about their break-up and left us all guessing. Perhaps lyrics on Tulisa's solo album will reveal all...?
