The redhead is back at Seattle Grace! ABC has confirmed that Kate Walsh, whose freshman show Private Practice is on hiatus until fall, will return to Grey’s Anatomy as Dr. Addison Montgomery for one episode this spring.

Executive Producer Shonda Rhimes is still fleshing out the script, so there’s no word yet on when Walsh’s episode will air.  ABC will air five originals of Grey’s beginning April 24.

The last time Addison was seen walking the hallways of Seattle Grace was in the series debut of Practice, which is this season’s second most-watched new drama (10.76 million).

In the Practice pilot, Addison said goodbye to Seattle Grace to start a new life and career at the Oceanside Wellness Center in Southern California.
