breaking newsIt's gone -- Katie Holmes has finally removed her wedding ring.
Holmes was photographed moments ago in NYC, as she left a "Project Runway" taping ... sans finger jewelry.
Katie had worn the ring as recently as last week -- just days before she filed for divorce from Tom on Thursday.
TMZ broke the story ... Katie believes her marriage to Tom became "irretrievably broken" at least 6 months ago -- so the fact that she was still wearing her wedding ring last week is another sign she intentionally blindsided Tom with divorce papers.
Further proof -- Tom was wearing his ring last week too.
