Is Matthew Broderick “average?”

His wife seems to think so – but only in one respect.

“Matthew is average,” Sarah Jessica Parker said on “The Late Show with David Letterman” on Tuesday, before turning to the audience and realizing her flub.

“Not in personality or intellect!” SJP said. “He’s average in height as I understand.”

The mother of three called their 7-year-old son, James Wilkie, “diminutive” – and blamed Matthew for his current size.

“That’s on my husband’s side,” she said. “[But]… the odds of our son being average in height and weight [are] pretty promising.”

However, she explained that James made up for his stature with his “brainiac” smarts, and was already planning his college choice.

”MIT. He got in, early admission!” SJP joked.

As for Sarah Jessica herself, fans can see her back in theaters on Friday in “Sex and The City 2.”
