Anthony Marentino is an event planner who becomes close to Charlotte after styling her first wedding.
Anthony freely doles out blunt, sometimes bawdy, advice to Charlotte York. Upon hearing that she hadn't had sex since her divorce, he exclaims: "If you don't put something "in there" soon, it'll grow over!"
In "The Real Me", Charlotte tries to set up Anthony and Stanford Blatch. Anthony snubs Stanford, which results in resentment and competition ensues for the entire show run. However, in Sex and the City (film), the two are seen kissing at a New Year's Eve party, and then get married in the sequel, with Anthony proclaiming at their wedding that Stanford is "the first man to accept me for the man that I actually am."
