Addison Montgomery is my second favorite female character on Grey's Anatomy because Kateis my second favorite actress not to mention that she is so beautiful. I love Grey's Anatomy mainly also because of Addison played by Kate Walsh and Mark played by Eric Dane. Even when Addison is played by Kate as a girl whose husband is still in love with his ex-girlfriend, I still love her. Addison has amazing chemistry with Mark played by Eric Dane. When Kate left the show, Addison was and still is my second favorite female character. Addison has been so great over the past five seasons because Kate Walsh has does an amazing job. I cried when she appeared and introduced herself to Meredith as Derek's wife and Kate played that scene well. I think it's one of my favorite scenes that Kate has done as Addison over the years. Addison Montgomery is and will always be my second favorite female character on Grey's Anatomy just like Kate Walsh is and will always be my second favorite actress on Grey's Anatomy.
