But do we believe them?  Last week Star magazine published a story about a 25-year-old woman who claims to have a had an affair with Matthew.  The couple has remained silent about the allegations and seemed to be happy as they went out for dinner in Manhattan last night.  Matthew and Sarah wore matching outfits, but what did not match were their ring fingers; Matthew did not have a wedding band on while SJP was seen earlier in the day with hers on.  Are Matthew's fingers just swollen from the summer heat or is there some truth to the rumors???

    

Matthew Broderick's 11-year-marriage to Sarah Jessica Parker could be on the rocks after explosive details emerged of his affair with a 25-year-old redhead. Matthew, 46, had trysts with the sexy youth counsellor at her apartment in New York's Upper East Side, and at the home of one of Matthew's own celeb pals, according to the latest issue of Star magazine. The couple became so close that the girl even had a nickname for Matthew - "Matty Cakes". And the report says on one occasion, Matthew grabbed the girl and kissed her passionately on the lips, before leading her upstairs to have passionate sex with her... Phew! Talk about sex in the city! According to Star the girl - who hasn't been ID'd - ditched Matty when he lied to her about where he was spending his Christmas vacation - in Hawaii with Sarah and his son, and not in Ireland alone as he'd told her. Matthew's rep declined to comment to Star about the claims of Matthew's cheating.

Matthew Broderick enjoyed some fun in the sun with his son James yesterday. And mini Mat even treated our photographer to a look at his groovy dance moves while they strolled around New York with the family pooch.

But no wedding ring. Hmm.  We caught Sarah Jessica Parker and Matthew Broderick walking around NYC last night.  Although the couple looks happy in their matching green pants, there have been rumors about a split and SJP is definitely not rocking her rock.  Well, as Justin Bobby would say "truth and time tell all".
