Deena Nicole Cortese was born on January 12, 1987, in New Egypt, a small town in New Jersey. She is best known for her role on the MTV reality series Jersey Shore, which follows eight housemates spending their summer together in Seaside Heights. Known for her outgoing personality and energetic presence on the show, Deena became a familiar face to audiences during its run. Her full name is Deena Nicole Cortese.
After graduating from New Egypt High School, Deena briefly attended Brookdale Community College. She has one sister, Joanie Maiorella, who also made appearances on Jersey Shore. The Cortese family is of Italian-American descent, a cultural background prominently represented on the series.
Though Deena was initially not cast in the first season of Jersey Shore, she joined the series in its third season, thanks in part to the recommendation of original cast member Nicole "Snooki" Polizzi. At the time, Deena was relatively unknown and working as a dental assistant, a job she has admitted she did not enjoy due to its academic demands.
Deena appeared in 54 episodes of Jersey Shore, and her wild, fun-loving behavior quickly made her a fan favorite. Outside of the show, she has appeared as herself in over a dozen other reality television specials and series. Over time, Deena has expressed that she has evolved from her earlier reality TV persona, describing herself as more grounded and mature today.

She adopted a structured exercise regimen and committed to a balanced diet. Within a year, she achieved notable weight loss and gained widespread attention for her transformation.
In addition to physical health, Deena made cosmetic updates, including dental work that led to a more polished smile. The change sparked mixed reactions among her fanbase—some preferred her original look, while others supported the update. Standing at 4 feet 11 inches tall, Deena embraces her petite stature and personal style as key parts of her public image.
Leveraging her popularity from Jersey Shore, Deena has developed a strong social media following across platforms like Facebook, Twitter, and Instagram.
