O'Keefe will play Kristina Coterra, a sultry and voluptuous entertainment reporter at WHNY who shows more than a professional interest in Castle in the second episode of the season, titled "Cloudy With a Chance of Murder."

Following years of will-they-or-won't-they romantic tension, Beckett was last seen leading her partner in crime to the bedroom following a steamy make-out session in the fourth season finale.
