Should we start calling it "Kastle"?
"ET" visited the set of "Castle" to talk with its People's Choice-winning star Nathan Fillion and former "One Tree Hill" actress Hilarie Burton about the Jan. 23 episode entitled, "An Embarrassment of Bitches."
On the episode, Burton plays Kay Cappuccio, a reality TV character inspired by the infamous Kim Kardashian.
"I'm the one guy who lives in a cave and doesn't actually follow the Kardashians," Fillion admitted to "ET." But, he added, "I think they're lovely people … We're not trying to hurt anybody's feelings."
Burton told "ET" that she's excited to step out of her typical role. "I don't think I've ever played a 'hot chick' before," she explained. "I always play the quirky friend or the really angry girl."

"Castle" airs Mondays at 10 p.m. EST on ABC.
