Ryan De Nino, who became known to reality TV audiences through Lifetime’s Married at First Sight, has died at 40.
A family member told TMZ that De Nino died suddenly earlier this week in New Jersey. His family has not released details about the circumstances surrounding his death.
De Nino first appeared on the reality series in 2015 during its second season, when he was 29 and working as a businessman.
His appearance on the show centered on his arranged marriage to Jessica Castro, whom he met for the first time at the altar.
News of his death has now brought renewed attention to the reality star’s brief but memorable time on television — and to the family members mourning him away from the cameras.
De Nino died earlier this week in New Jersey, according to a family member who spoke to TMZ.
The circumstances surrounding his death have not been disclosed, and his family is not releasing additional details at this time.
His sister, Melissa De Nino, shared a personal tribute following his death.
“Life as I know it will never be the same,” she wrote, reflecting on the loss of her brother.

Melissa also described Ryan as funny and witty, fiercely loyal to the people he loved and someone with a big heart.
For viewers who remember De Nino from Married at First Sight, his television story began in the show’s second season in 2015.
At 29, he entered the experiment alongside a group of strangers willing to marry partners selected for them by the show’s relationship experts.
De Nino was matched with Jessica Castro.
The pair met for the first time at the altar, following the show’s unusual premise of marrying before getting to know one another.
Despite the unconventional beginning, Ryan and Jessica initially chose to remain together when they reached the show’s “Decision Day.”
Their marriage, however, eventually ended in divorce.
The relationship became a major storyline surrounding their season, and their split later became contentious.
For now, though, De Nino’s family has asked for privacy regarding the circumstances of his death.
That leaves his sister’s tribute and his television legacy as some of the few public windows into the man remembered by Married at First Sight viewers.
De Nino became part of Married at First Sight during the show’s second season, which introduced him to a national reality-TV audience.
His relationship with Castro was one of the season’s central stories, beginning with their unusual first meeting at the altar and continuing through their decision to remain married on the show’s designated decision day.

Their marriage ultimately did not last.
After the relationship ended, the former couple’s split became controversial and attracted additional public attention. However, those later disputes are separate from the circumstances of De Nino’s death, which his family has not disclosed.
De Nino subsequently lived largely outside the reality-TV spotlight.
His death at 40 therefore represents a sudden loss for his family and a sobering moment for viewers who remember him from the Lifetime series.
Reality television often gives audiences an unusually intimate introduction to people whose lives continue long after filming ends.
That was the case with De Nino.
His appearance on Married at First Sight made him recognizable to viewers in 2015, but his life after the series was largely lived away from television.
His death now brings attention back to the Season 2 cast and the unconventional experiment that introduced him to the public.
It also highlights the difference between what viewers see on reality television and the private lives participants lead after the cameras stop rolling.

At 40, De Nino’s death is particularly striking because so little is publicly known about what happened.
His family has chosen not to release those details, and there is currently no confirmed cause of death in the information available.
Following the news, De Nino’s sister Melissa shared an emotional tribute reflecting on their relationship.
She described the pain of losing a sibling and emphasized the lifelong connection they shared.
“Life as I know it will never be the same,” Melissa wrote.
Former Married at First Sight viewers have also begun remembering De Nino and discussing his time on the series, while his former wife, Jessica Castro, has publicly addressed his death as well.
The family’s decision not to disclose the circumstances surrounding his death remains unchanged.
Behind the reality-TV personality was a son, brother and family member whose loss is now being felt privately by those closest to him.
Melissa’s tribute focused not on his television appearance, but on the person she knew throughout her life.
Her words underline the depth of a sibling relationship and the sudden disruption caused by losing someone who has been part of your story from childhood.
For audiences, Ryan De Nino may be remembered as a Married at First Sight groom.
For his family, he was much more than the person viewers saw on television.
Ryan De Nino’s Married at First Sight journey made him a familiar face to reality-TV viewers, but his family is now mourning a 40-year-old brother and loved one whose sudden death remains unexplained publicly.
