From "'Grey's'/'Private' exclusive: Meet Derek's kid sister!"
How’s this for a twist: Shonda Rhimes is introducing Derek Shepherd’s kid sis, but not on Grey’s Anatomy.
Sources confirm to me exclusively that Caterina Scorsone (Lifetime’s 1-800-Missing) is joining — wait for it — Private Practice in the recurring role of Dr. Amelia Shepherd, one of Derek’s never-before-seen sisters.
I’m told the character — nicknamed “Little Shep,” natch — lands a job at Oceanside Wellness.
Currently, there are no plans for Patrick Dempsey to cross over to PP to hang with his sibling, but a family reunion — most likely right at the start of sweeps — is inevitable.
