'Smallville' alum heading to 'Castle'
Hartley will guest star in an upcoming episode of "Caslte," TVLine reports. The man otherwise known as the Green Arrow will play the boyfriend of a reality TV celebutante in the 13th episode of Season 4, called "An Embarrassment of Bitches."
We're not sure what the case involves other than Hilarie Burton playing Kay Cappuccio, a Kardashian-like socialite who struggles with her fame, but knowing "Castle," we're sure it'll be a funny take on reality TV stardom.
"Castle" returns with a new episode on Dec. 5. Episode 13 is scheduled to air in 2012.
