90 Day Fiancé star Chuck Potthast has passed away at the age of 64.
Chuck, who was the father of Elizabeth ‘Libby’ Castravet, was featured on the fifth season of the TLC reality show.
Elizabeth and her husband Andrei made their debut on the show in 2017 and have also appeared on the spin-off, 90 Day Fiancé: Happily Ever After?
On Sunday, November 23, Elizabeth shared the devastating news about her father’s passing through a joint Instagram post with her husband Andrei.
“Two weeks ago, tragedy struck our family and it has left us completely shattered,” she expressed.
“My sweet, loving, and caring dad went to heaven. We’re trying to figure out how to navigate our lives and move forward without him.”
“Please respect our privacy during this extremely difficult time.”
Since 2022, Chuck had been fighting glioblastoma, a type of brain cancer.
He kept his followers updated about his health through social media, including details about a hernia surgery in September, which extended to an eight-hour operation due to complications related to previous cancer treatments.
Chuck managed a rental property and home flipping business, CMP Capital Investments.
He and his ex-wife Pamela had seven children together: Elizabeth, David, Charles, Daniel, Michael, Jennifer, and Becky.
Becky also honored her father on Instagram, posting a photo of them from her wedding day with the caption: “Two weeks ago on this day my world became distorted into a place I don’t understand. My father Chuck went home to be with The Lord. The pain is still more than I can bear so this is all I can write.”

According to Mayo Clinic, glioblastoma is a swiftly growing, invasive cancer that begins as a growth of cells in the brain or spinal cord.
While it can occur at any age, it primarily impacts ‘older adults.’
The American Brain Tumor Association reports that over 12,000 glioblastoma cases are diagnosed annually in the United States.
Mayo Clinic has identified 11 symptoms to be aware of, which can present both physically and mentally.
A primary symptom is a headache, particularly those that are most painful in the morning.
Patients may also experience vision changes such as blurred vision, double vision, or loss of peripheral vision.
Other symptoms can include nausea, vomiting, and difficulty with speech.
Seizures, especially in those with no prior history of seizures, may signal glioblastoma.
Furthermore, problems with balance or coordination, muscle weakness in the face, arms, or legs, and reduced sensation of touch could be indicative.
Other signs might encompass personality changes, irritability, confusion, and memory loss.
