Question: I read AA every week! Do you have any Smallville scoop? ? Paul

Ausiello: Carrie's playing Pauline Kahn, the no-nonsense editor-in-chief of the "Daily Planet" whom Chloe (Allison Mack) meets in hopes of landing an internship. Her episode airs Oct. 27. But considering Chloe gets the gig, it's probably safe to say we'll see Princess L again.

Thanks to Scott, who knows I like Smallville. ;-)
