Well, what do you know - Addison Montgomery has gone and made herself a new friend on Private Practice, reports TV sleuth Michael Ausiello over at EW.

What About Brian's Amanda Detmer has booked a four-episode arc on the Grey's Anatomy spin-off playing a pregnant patient of Kate Walsh's character.

But what begins as a professional relationship gradually turns personal when the two strike up a friendship. Sounds like a refreshing change for Addison!

Look for Detmar to debut in March.
