Rumors Sarah Jessica Parker and Matthew Broderick's marriage is on the rocks are refusing to go away - a U.S. tabloid now alleges the Sex And The City star is ready to move out of the family home.

Back in August, Star magazine alleged Broderick, 46, had an affair with a younger woman. The couple issued no comment, and quickly put on a united front, posing for photographs together.

However five months on, the rumors are back, with Star now claiming the couple attempted to save their 11-year marriage for the sake of their four year old son James Wilkie - but are now preparing to go their separate ways.

An insider tells the magazine, "Sarah Jessica is determined to get her own place and bring down the curtains on her marriage. They're essentially living separate lives. The truth is, Sarah and Matthew still do love and care about each other, they just aren't in love, and they don't want to waste any more time trying to repair something that's irreparable."
