ABC has booked Alyssa Milano to guest star on “Castle” in early 2010.
Milano is set to play mystery novelist Richard Castle’s ex-lover, which is sure to bring out the ugly green monster of jealousy in Castle’s writing inspiration, Detective Beckett. Milano is to make her appearance in an episode titled ‘A Rose for Everafter’.
No premiere date for Milano’s “Romantically Challenged” has been announced by ABC yet.
The network recently picked up “Castle” for a full second season.
