Star Magazine reports that Sarah Jessica Parker has finally left husband of 11-plus years Matthew Broderick.

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

The split stems from an alleged affair with a 25-year-old youth counselor who, according to a pal, nicknamed Broderick “Matty Cakes.” So not only does life sometimes imitate art, but apparently it also imitates “Sex and the City” on occasion.

Filly-faced Sarah Jessica Parker is leaving the Beaver look-alike behind and moving on to greener pastures, which should excite the diminuitive real-life “Mr. Big,” who can now court his young thang and “Inspect her Gadget” without fear of being caught.

There is no indication what will happen with the couple’s six-year-old son.
