“90 Day Fiancé” star Ben Rathbun has died after a battle with stomach cancer. He was 55.

Rathbun died at his home in Greencastle, Indiana, on Monday morning. His wife, Mahogany Roca, and other family members were by his side when he passed away, as reported by TMZ.

The outlet reported that the former reality TV star had stage 4 stomach cancer and had been battling the disease since he was diagnosed at the end of last year.

Several “90 Day Fiancé” franchise stars took to Instagram to pay tribute to Rathbun after his death.

“This is truly sad. He made mistakes as we all have but he is a good guy. I pray for him and his family,” Kim Menzies wrote under blogger Shabooty’s Instagram post.

“omg. 😳 this is so sad to see him or anyone die from cancer. prayers to him and his family and mahogany. #f–kcancer,” added Mike Berk.

“Damn this is so sad. We never know what someone is going through,” commented Tyray Mollet.

Rathbun starred on Season 5 of “90 Day Fiancé: Before the 90 Days,” which aired on TLC from December 2021 to April 2022.

He met Roca online and they virtually dated for three months before they joined the hit reality show together.

Rathbun, who was a Michigan native, traveled to Peru to meet Roca for the first time — despite his family and friends raising concerns over speculation that she might be a catfish and their 30-year age gap.

Roca and Rathbun announced their engagement in August 2022.

During a February 2024 episode of “90 Day Diaries,” they revealed that they tied the knot.

“Our civil ceremony was just brilliant, I could not believe how beautiful it was,” he said as photos from their ocean-front wedding were shown.

Rathbun leaves behind four children, whom he shares with his ex-wife, Lisa.
