In a recent Jersey Shore: Family Vacation episode, Deena Cortese missed out on a group trip due to her son's coxsackievirus diagnosis, and it's time to share information about this health issue. Although Deena was not one of the original Jersey Shore roommates, she is treated like an OG cast member. She started filming with the cast in season 3 of the original show, and over the years, Deena has grown and matured, just like the rest of the "roomies." Viewers have also been introduced to Deena's husband, Chris Buckner, as well as their two sons, CJ and Cameron.
