As previously revealed, Castle will soon rip a storyline straight from the headlines:

Tom Bergeron will guest star on on episode this spring, playing Bobby Mann, a talk show host that's murdered by the comedian (Bill Bellamy) who wants his time slot.

We can now confirm that Kelly Carlson will appear in that same installment as love interest for Nathan Fillion’s title character.

According to Entertainment Weekly, Carlson will portray an actress named Ellie Rose. She meets Castle on the set of Mann's late-night talk show.

Fred Willard will also appear on this special Castle episode (as Bergeron’s sidekick), as will French Stewart and Dan Cortese.

Carlson is best known for her long-running role on Nip/Tuck. She's also appeared recently on CSI: Miami and Melrose Place.
