Ellen Pompeo and Patrick Dempsey have extended their contract with ABC, signing a new two-year deal with hit medical series, Grey's Anatomy. Though the Shonda Rhimes drama is yet to be renewed for 2014, it's now safe to assume that Pompeo and Dempsey are not leaving the series until seasons 11 and 12.
No word yet on other original Grey's cast members: Justin Chambers, Chandra Wilson, James Pickens Jr. and Sara Ramirez whose contracts are also set to expire at season’s end.
In 2013, Sandra Oh who portrays Cristina Yang announced that she has decided to exit the series after 10 years.
