According to sources close to the

her a 'marry me or lose me' ultimatum but she wasn't convinced he could
be trusted.

Tulisa was said to be especially concerned with her N-Dubz bandmate's relationship with former Made In Chelsea star Chloe Green.

According
to an insider Fazer and Chloe, who met through mutual friends, were
texting each other when the 25-year-old was recently on holiday with
Tulisa.

After Tulisa confronted him about the Topshop heiress he is then alleged to have questioned her commitment to their relationship.

A friend told Closer magazine that Fazer said: 'I want marriage and a baby and it seems all you want is fame!'

The
insider told the publication: '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.'

Fazer, real name Richard Rawson, is also said to have asked the chart topper to quit her role on X Factor.

A
source told heat magazine: '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.'

Earlier this week, Tulisa confirmed that she will be releasing a solo single in the next few months.

With her group N-Dubz on hiatus and her recent split from Fazer, it's the perfect time for Tulisa.

She told London radio station Capital FM: 'I've got my single ready now to release. I'm going to be shooting a video soon.

'Haven't got a set date but I'd say within the next two months definitely.'

And
despite singing urban songs with her N-Dubz band-mates Fazer and
Costadinos 'Dappy' Contostavlos, Tulisa's solo sound will be a little
different.

She explained:
'It's very me but maybe not what people would expect genre-wise. It's
one of those tracks that you don't get bored of.'

Aside
from her solo work, Tulisa is rumoured to be duetting with her 'little
muffins' Little Mix on a track for their debut album.
