The 42-year-old insists she quit the popular Bravo franchise because she is 'tired of the fighting and cattiness'.
However, there are some rumours she was fired over her diva behaviour and demands for more money.
'After four solid seasons of helping Bravo build the show into its most successful Housewives franchise, I have decided to leave,' she tells the TV website WetPaint.
'The direction the show is going in is no longer a fit for my lifestyle. I'm tired of the fighting and the cattiness.'

It's quite the turn-around for Sheree, who famously pulled Kim Zolciak's wig in the second season.

A source told the website: 'Sheree was fired.She was demanding more money and that didn't go over well with show executives. They are tired of dealing with her diva attitude and demands.'
