There’s only one thing more entertaining than Liza Minnelli: Kristen Wiig playing Liza Minnelli. Since the latter is busy with other funny business, NBC announced Tuesday that they are bringing in the Queen of Broadway herself to guest star on Smash, returning Feb. 5. The episode, titled “The Surprise Party,” will feature Minnelli singing an original song with regular Christian Borle. NBC Entertainment chairman Robert Greenblatt says the legendary Minnelli is a “perfect fit” for the Broadway-themed drama. Other notable A-listers scheduled to appear on Smash this season include Jennifer Hudson, Jesse L. Martin, Sean Hayes, and Bernadette Peters.
