Matthew Broderick Cheating on Sarah Jessica Parker Rumors

With the Madonna and A-Rod affair chatter cooling down, rumor has it that Matthew Broderick is cheating on his wife Sarah Jessica Parker. I seriously hope that this turns out to be mere gossip because Matthew, Sarah and little James, 5, seemed like such a solid family.
Star magazine is claiming that Matthew indeed cheated on Sarah Jessica with a 25-year-old woman.

"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," a source told the magazine.

I'm sure we'll be getting a statement from their PR spin doctors completely denying the allegations. Could there be any truth to the rumors after 11 years of marriage?
