I hope this is not true!  Here’s what Star has to say:

Sarah Jessica Parker’s husband has been sneaking off for hot trysts with a stunning redhead half his age, sources tell Star in a blockbuster exclusive.

Star reports that while the beloved actress was frantically searching for hubby Matthew Broderick one night earlier this year, he was having sex in the city with a gorgeous redhead half his age, the young woman told a friend.

After meeting in a bar, Matthew began text messaging the 25-year-old youth counselor, says the woman’s pal. Soon after, the insider claims, they began seeing each other and things got passionate quickly when they met at the Manhattan townhouse of a showbiz friend.

Sources say the woman felt conflicted with her relationship with Matthew, whom she nicknamed “Matty Cakes.” She tried to end it, say insiders, but that didn’t happen and over the next month — when Sarah Jessica was filming Sex and the City: The Movie in Los Angeles — multiple eyewitnesses say they saw Matthew make late-night visits to the other woman’s apartment building.

During one tryst, they arrived at her friend’s apartment after a night of heavy drinking, says a source. She dragged Matthew into the friend’s bedroom, then shut the door. “A half hour later, Matthew opened the bedroom door, mumbled ‘Well… ‘bye!’ and walked out. The friend found her passed out on the bed in her panties.”
