Grey's Anatomy Lesbian Doctor Canned

Brooke Smith -- better known to Grey's Anatomy fans as Dr. Hahn -- has been suddenly canned from the show, and some are claiming that it's directly related to the fact that her character is gay.

With Dr. Hahn being one half of what was the only lesbian couple on prime time television, should we expect Rosie O'Donnell to make an appearance sometime soon? (Note to Rosie: Please reprise the role of Riding The Bus With My Sister's Beth Simon, in which your choice of playing "mentally retarded" meant doing a 90-minute impression of Cookie Monster).
