New Cast Member Added to Grey's Anatomy

Chyler Leigh has been added as a full-time staffer at Seattle Grace. She has made brief appearances as Meredith's half-sister, but reps at ABC Studios have confirmed that she is now going to be a series regular with the start of the new Fall season. Guess they had a little slush fund money leftover with the permanent departure of Isaiah Washington.

You might recognize the North Carolina native from appearances on That 80's Show, The Practice and Reunion.
