Will & Grace star Megan Mullally will guest star in an upcoming episode of ABC's Boston Legal.
Mullally, who played Karen Walker in the NBC sitcom for 8 years, will join Boston Legal as Renata Hill, a former love interest and co-worker of Alan Shore (James Spader).
Of Mullally's role, ABC has announced: "No stranger to trouble, Renata reunites with Shore as she dashes down the courthouse hallway wearing a bloody wedding gown, carrying a bloody pair of scissors and proclaiming her innocence in the murder of her betrothed."
The episode, "The Bride Wore Blood," will air later this season.
