Ferris Bueller’s having an affair. A Star Magazine snitch has accused actor Matthew Broderick of having lots of sex in the city with someone other wife Sarah Jessica Parker. Matthew is reportedly cheating on television’s “Carrie Bradshaw” with a petite redhead more than 20 years his junior.

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.
