Castle has landed a pair of talented, beautiful guest stars.

On the November 23 episode of the show, Abigail Spencer (most recenetly seen on Mad Men) will play a murder victim’s fiancée.

There's just one problem: Perrey Reeves (Mrs. Ari on Entourage) turns up as the victim’s wife. As you can imagine (and get excited for, fellas), catfighting ensues!
