This sounds like a bad episode of poor Sarah Jessica Parker's famed HBO show!

Star Magazine reports that the Sex and the City actress' hubby, Matthew Broderick, has been having an affair "with a gorgeous redhead half his age," says an inside source.

Apparently, Matthew met the 25-year-old youth counselor in a bar, began text messaging and then seeing each other during "late-night visits to the other woman's apartment" - and all this while SJP was filming SatC: The Movie!

Another source also claims that the woman took Matthew to a friend's apartment one night, "dragged Matthew into the friend's bedroom, then shut the door." Matthew emerged a half hour later, murmuring "well... bye!" before heading out.

Now Parker and Broderick, who have a son (James Wilkie) together, might be headed towards Splitsville. Think the story is true?

So sad - these two seemed to have the perfect marriage!
