Controversial, frequently absent Grey's Anatomy cast member Katherine Heigl may be returning  to the halls of Seattle Grace Hospital, but she won’t be doing it as a blonde!

The actress stepped out for lunch yesterday in L.A. as a brunette, and while Katherine has become one of Hollywood’s most noteworthy blondes, the dark 'do does the job.

It may not be her signature look, but we like the length as well, and sometimes, a little change is good. We just wonder if Izzie Stevens will now become brunette, too.
