Actor alleged to have had fling with unnamed woman
The actor is alleged to have had a fling with an unnamed woman from November 2007 to February this year, while Sarah was filming her latest movie.
He is reported to have met the 25-year-old at a New York bar.
Matthew, 46, is said to have convinced the woman that the alleged tryst was okay because his marriage to the Sex And The City star was on the rocks, according to American mag Star.
He and Sarah, 43, who have been married for 11 years, have a son, James Wilkie, 5.
Matt’s spokesman Simon Hall declined to comment.
