Ryan De Nino, who was featured on the second season of the A&E reality series "Married at First Sight," has died at the age of 40. A family source informed TMZ that De Nino passed away "suddenly" in New Jersey.

Further details regarding the cause of death have not been released by his family. De Nino's sister, Melissa, shared a tribute on Facebook earlier this week, remembering him as "funny and witty" and "fiercely loyal."

De Nino was paired with Jessica Castro on "Married at First Sight" in 2015. They stayed together until the show's "Decision Day" but later divorced.

In 2015, Castro filed for a restraining order against De Nino, alleging he had threatened her and her family, according to People. De Nino, who was active on Instagram and had over 40,000 followers, last posted on the platform in June 2022.

Castro issued a statement expressing her condolences to De Nino's family, stating she had not been in contact with him for years. She offered her "sincerest condolences to his family during this very difficult time."
