Brandi Glanville’s father, Guy Glanville, has died at age 77.

“My dad died, I’m gutted I hate this life right now,” the former reality TV star, 53, wrote via X on Saturday alongside a broken heart emoji.

Brandi did not reveal Guy’s cause of death and her spokesperson did not reply for comment.

The former model had a rocky relationship with her father, including periods of estrangement, following their appearance on “Marriage Boot Camp: Reality Stars Family Edition” in 2018.

“My dad and I, we left the show in a great space and then, when the show aired, we haven’t talked since,” Brandi told “Entertainment Tonight” shortly after the show’s season premiere.

“You know, he’s not done TV before, and I warned him ahead of time, ‘They’re not going to be able to show everything that we shot. They’re going to show the highlights, so you have to write down notes and understand it’s going to be the highlights of what we shot, and don’t get mad — you’re gonna get mad all over again,’ and ultimately, he did.”

The “Celebrity Big Brother” alum added they hadn’t talked, but said she “love[s] him dearly.”

“He’s everything. I’m just, I’m leaving [it] in his corner. Because you know, you know me, I get a little aggressive,” she shared.

Brandi and Guy eventually reconciled and he even defended his daughter during her feud with her fellow Bravo star Denise Richards.

“My daughter may be many things, sometimes an a–hole, but she is not a liar,” Guy said in a video shared via Instagram at the time, according to Us Magazine.

Earlier this year, Brandi revealed that her father was not doing well.

“Been completely off the grid,” she wrote via X. “Dad in cardiac unit at the hospital & it’s day 13 now. We are both medical mysteries. Pray for my dad Guy Glanville.”

The “Drinking & Dating” author has also been battling serious health issues with unexplained problems affecting her face.

The television personality recently shared ultrasound footage on Instagram, saying her doctor “saw something alive” and “moving” in her face during the examination.

“If I don’t find a doctor to cut this out of my face, I’m just going to do it myself,” she said in the video.

Brandi said she has “highly resistant ESBL Klebsiella and Enterobacter with biofilm, Coccidioidomycosis (Valley fever), Demodex dermatitis and mononucleosis.”

She also said she has a fungal ball in her face that she is preparing to have removed.

In February, Brandi blamed her health issues on her 20-year-old ruptured breast implants, which she said had leaked silicone into her lymph nodes.

Though the Bravo star said her medical bills are totaling seven grand a week, she recently shared she felt “embarrassed” that a GoFundMe had been set up in her name by a friend.
