Ian Somerhalder told me at the People's Choice Awards that he'd just shot a Vampire Diaries scene where Damon "wakes up naked with another woman who is a hot vampire." Might this be Katherine? Nina Dobrev (Elena/Katherine) hints, "I can't say whether or not I'm in that scene, but it is a character fans are familiar with and Elena will definitely have an opinion on it."
Question: I need some House scoop!
Answer: Producers have cast House's parents — and they're two people I've never heard of! Diane Baker (A Mighty Wind, HBO's Unscripted) and R. Lee Ermey (Full Metal Jacket) have been tapped to play Blythe and John House. They'll turn up in the fifth episode.
