Eddie Cibrian (CSI: Miami, Ugly Betty) will guest star on TNT's RIZZOLI & ISLES. He will play Dennis Rockmond, a handsome motivational speaker who is introduced to medical examiner Maura Isles (Sasha Alexander) in the most unusual way. Maura then becomes intrigued with Dennis when he brings out her wild side.
Cibrian is best known for his television role as patriarch Cole Deschanel on Sunset Beach, which gained popularity for the actor in the 1990's. He has appeared as Jesse Cardoza in CSI: Miami, Jimmy Doherty on Third Watch and Russell Varon in Invasion.
Based on characters created by best-selling crime novelist Tess Gerritsen, RIZZOLI & ISLES stars Angie Harmon as Jane Rizzoli, a tough-as-nails Boston police detective, and Sasha Alexander as Maura Isles, a smart, impeccably dressed medical examiner from a privileged background. Despite being complete opposites, the two women share an offbeat chemistry and strong working relationship that has helped them bust some of Boston's most notorious criminals.
Lorraine Bracco stars as Jane's demanding and intrusive mother, Angela. Lee Thompson Young is Detective Barry Frost, Jane's somewhat green partner. Bruce McGill plays Detective Vince Korsak, Jane's seasoned former partner who resents her being paired with Frost. And JorDan Bridges is Jane's brother, Frankie Jr., a patrol cop who hopes one day to become a detective.
