Minor Surgery on "Private Practice"

Your eyes won't be playing tricks on you. Come this fall when the Grey's Anatomy spin-off Private Practice makes its debut, there's something different about Dr. Addison Montgomery's best gal pal. Merrin Dungey, formerly of Alias fame, has been replaced as Dr. Naomi Bennett by four-time Tony winner Audra McDonald. Word has it that one of the criticisms of the show, which was part of an extended episode of Grey's, was a lack of chemistry, namely between Dungey and Kate Walsh.

Since McDonald and Taye Diggs, who plays her ex-husband and partner in the medical practice, both have Broadway ties, is there a possible karaoke night out for the whole office? Tune in to ABC this fall to find out!
