Sarah Jessica Parker: Moving Out On Matthew?

Sarah Jessica Parker is reportedly shopping around for a new home in Manhattan.

Star reports that SJP is moving out on husband Matthew Broderick, possibly due to this past summer’s allegations of an affair on his part.

The Sex and the City star, 43, is allegedly consulting a real-estate broker to find her own place in the city. The couple share a son, James Wilkie, who is 6 and goes to school in Manhattan.

“The time has come when she realizes it just isn’t worth it,” a “friend of the couple” said. “Sarah Jessica is determined to get her own place and bring down the curtain on her marriage.”

The magazine also cites another source as claiming the two live “separate lives.”

Parker has had a rough time of it ever since tabloids began blaring that Broderick, 46, cheated on her in New York City while she was filming her blockbuster Sex and the City movie in Los Angeles.

She also recently weathered the distraction of having to rein in her co-star Kim Cattrall when Cattrall announced on British television that the sequel to the movie was a done deal.

Parker, a fashionista icon as both herself and her SATC character Carrie Broadshaw, issued a statement to Cattrall’s contrary.

Here’s Parker wearing a coral coat over a tank top that seems to read “CHANGE.”

Could she really be making one?
