Castle Spoiler: Soap Vet Nancy Lee Grahn to Guest Star as Wealthy Divorcee in Season 5

Brace yourselves for some relationship drama of epic proportions, Castle fans! This January, it'll be a War of the Roses-style battle for two star-crossed lovers. 

Relax, Caskett 'shippers! We're not talking about our ruggedly handsome secret lovers. We're talking about a recently divorced socialite named Samantha Voss, played by General Hospital vet Nancy Lee Grahn, who finds herself in a "hilariously ill-witted" battle with her ex-hubby, played by Weeds actor Brendan Ford.

According to TVLine, the episode is called "Significant Others" and slated to air sometime after the new year.

We don't know much about these warring ex-lovers, but they're somehow connected to Castle and Beckett's murder investigation. Fellow soap star Jack Wagner has been tapped to play a famous golfer whose wife is found dead.

We smell a scandalous affair! What do you think, Castle fans? Any early predictions about "Significant Others"? Tell us below!
