Sarah Jessica Parker is terrified a divorce will leave her penniless.

The 'Sex and the City' actress - whose 11-year marriage to actor Matthew Broderick is reportedly on the rocks following allegations he cheated on her with a 25-year-old beauty - is giving her relationship another go because she doesn't want to lose the multi-million pound fortune she has accumulated.

A source told Look magazine: "Sarah's family were poor when she was a child. She had seven brothers and sisters and she's often talked about missing out on birthday presents when she was young.

"It seems she's freaking out over the thought that Matthew could walk away with an enormous sum of money."

It was recently reported the couple - who have a six-year-old son James Wilkie together - are leading separate lives.

They put a united front on over the festive period for the sake of James, but their Christmas truce is said to have caused further cracks in their relationship.

Another source added: "They spent the holidays pretending to be happy for James."

Sarah, 43, is reported to have earned a staggering £110 million during her career, and her earnings have far outweighed Matthew's during their union.

Her fee for the upcoming sequel to 'Sex and the City: The Movie' is expected to be around £35 million.
