Keri Lynn Pratt will be Cat Grant

Meet Clark Kent’s new partner at the Daily Planet

Question: I’m about to go Mel Gibson on your butt if I don’t get some Smallville spoilers regarding Lois and Clark. So how ’bout it bud? —Christine
Ausiello: You wouldn’t dare hit a man while he’s holding a mint condition Vanity Smurf plush circa 1982, would you? [Beat] Don’t answer that. Okay, here’s your scoop: There’s a development in the premiere that is so ginormous you’d think Smallville was heading into its final season or something.

Question: Any intel on Smallville‘s big bad this year? —Mitch.
Ausiello: No, but I think I have something better: Clark’s getting a new partner at the Daily Planet this season, and she’s got some major DC Comics cred. The character’s name is Cat Grant, and my good buddy Walter Wikipedia has all the deets on the currently-being-cast character. (And no worries Clois fans; Cat will serve solely as a comedic foil to Clark. I think.)
