Castle Scoop: Hilarie Burton Excited to Tackle a 'Radically Different' Kind of Role

Hilarie Burton is set to guest-star on Castle at midseason, and the actress tells me the gig has her excited for multiple reasons — one being that she is “definitely a fan” of ABC’s Monday-night cop drama.

Burton also points out that her Castle episode will play host to a One Tree Hill reunion of sorts, seeing as Tom Wright — who directed several episodes of the CW sudser — will be calling the shots as she plays Kay Cappuccio, a Kardashian-like reality star who is famous for… well, no discernible reason.

“He is one of my favorite One Tree Hill directors, so I’m really looking forward to working with him again,” Burton effuses. “And this time playing someone so radically different!”
