Lisa O'Connor/ZUMAPress.com "She started today, and she's terrific."
That's the word from a reliable Samantha Who? insider on the show's latest guest star: Mary-Kate Olsen.
After a tip-off from on-set sources, ABC has just confirmed that Mary-Kate is shooting an episode of the divine, good-versus-evil comedy this week, playing a character whom Samantha (Christina Applegate) tries to "save." (Score one for Good Sam.)
I'm told M.K. is only slated to do one episode (airing this fall), and the powers that be are very happy with her performance so far.
Of course, if you saw Mary-Kate tormenting Silas on Weeds last season, you know the girl has serious comedy chops. (Word is she also did some show with a guy named "Uncle Jesse"? Doesn't ring a bell.)
And given the recent news that James Yummer, er, Tupper will also appear in the second season, only one question remains: Is it fall yet?! Holler with your Sam Who? anticipation below.
