''Will and Grace'''s Leo and Grace are a hot TV couple

PLAYED BY Debra Messing and Harry Connick Jr.

RELATIONSHIP STATUS They impulsively tied the knot in a stunt mass wedding on the ”Today” show after dating for just a few months; when they found out the marriage wasn’t legal, they got hitched in a white wedding, broadcast — surprise! — just in time for November sweeps.

WHY WE LOVE THEM Leo fits right in to the antic ”W&G” world of Will, Grace, Jack, and Karen.

WHY WE DON’T Connick’s guest-star status this season leaves Grace with too much alone time. The coupling feels like an ill-conceived impediment to the ”Will and Grace having a baby” subplot, and the writers don’t seem to know what to do with it.
