Chuck Potthast‘s son apparently found his body … and he told the 911 operator his dad was bleeding heavily — and didn’t look alive.

We’ve obtained the audio of the 911 call … which begins with a man identifying himself as Chuck’s son — and telling the 911 operator his father’s lying in the bathtub and bleeding from the chest.

Potthast’s son says he doesn’t know what happened to his father … and, when the operator asks him if he’s awake, he responds by saying he doesn’t think Chuck even looks alive.

As you know … Elizabeth Castravet — Potthast’s daughter who also appeared on ’90 Day Fiancé’ — announced her father’s death last month, posting on social media that the whole family’s “devastated” after the loss. His other daughter, Rebekah Lichtwerch, paid tribute to their father as well by writing that her world has been “distorted into a place I don’t understand.”

Chuck was open about his health struggles in recent months … posting in September about an 8-hour surgery he underwent to repair a hernia and a collapsed stomach. It’s unclear if these same health issues played a role in his death.

Potthast was 64.

Noah Weiland is doing alright after making some nerve-wracking posts on Instagram Thursday … with a family friend coming to his aid during what seems like a time of crisis.

Tim Ryan — a friend of the Weiland clan — tells TMZ … he spent all Thursday afternoon and evening with Noah after he posted about his own death on IG, and the 25-year-old is doing fine.

We’re told the son of Scott Weiland has spoken to his mother, Mary Forsberg, since sharing the posts, and she’s aware he’s safe.

ICYMI … Noah shared a blurry gray photo with white words written on top, which began with “I’d rather be DEAD then live as my father did.” He then followed it up by writing that he can’t wait to see his dad again and thanking everyone for their support.

He also set another Instagram story post to the Green Day song “Last Night on Earth” … seemingly a foreboding message about possible suicidal ideation.

Scott Weiland — lead singer of Stone Temple Pilots and Velvet Revolver — was found dead on a tour bus in 2015. He overdosed on a combination of cocaine, MDMA and alcohol. Noah recently took the stage to play some of his dad’s hits in honor of the 10th anniversary of the late star’s death.

Aubrey O’Day had a recent medical scare … and that’s the reason she had to skip the Danity Kane reunion show Wednesday in Los Angeles, a stop on the group’s comeback tour.

On her Instagram Story, Aubrey explained she was hospitalized after feeling sick all day … fighting her undisclosed symptoms until she finally had to go to the ER — saying she was “heartbroken” to let fans down.

Aundrea Fimbres and D. Woods ended up performing as a duo at the El Rey Theatre … the second stop on Danity Kane’s “The Untold Chapter” tour, which was announced in October.

Aubrey has been in the news lately because she appeared in 50 Cent’s Diddy documentary on Netflix … reading a sexually charged email allegedly from Diddy … and said she believes she was fired from the “Making the Band 3” group because she refused to sleep with him.

Along with the health scare … the singer posted to IG on Thursday that it had been a “heavy time” for her — and that it was stressful for fans to finally hear in the Netflix doc “things that were hard for me to say.”
