New Guest Stars for Grey's Anatomy

With an upcoming spin-off in the works, and the recent uproar over salary negotiations, there's certainly a lot going on at Grey's Anatomy these days. The producers have just signed on two new guest stars, set to appear on the drama this Spring. Michael Boatman (Carter Heywood from Spin City) and Catherine Dent (of The Shield) will both be making appearances.
