This hurts. The spectacular Eileen Davidson has chosen to leave her role as whackjob villainess Kristen DiMera on NBC's Days of Our Lives and will last be seen during November sweeps. TV Guide Magazine landed the first exit interview with the actress, who reveals why she's taking a hike from a gig that's winning her wide acclaim. How come Days didn't try to keep her? Will she return to CBS's The Young and the Restless and her role as Ashley Abbott? And why, dear God, are you doing this to us?
