Stephanie Buttermore dies at 36 after 'long' disappearance

Fans are mourning the death of fitness  influencer Stephanie Buttermore, who died at the age of 36. Buttermore's death was announced by her fiancé Jeff Nippard on social media. 

Nippard’s team posted the news of Buttermore's death in a statement shared to Instagram on Friday.  No information on her cause of death has been made public.

“It is with profound sorrow that we share the sudden passing of Jeff’s fiancée and partner of ten years, Stephanie,” the post read. “As many of you know, Stephanie meant the world to Jeff.”

From her long disappearance from social media to her grey neck in Valentine's Day photo, Stephanie Buttermore's death has led fans to speculate about their favorite influencer's death despite her fiancé Jeff Nippard requesting privacy.

According to her YouTube channel, she was a cancer research scientist who earned a Ph.D. in pathology and cell biology “with a focus on the molecular mechanisms that drive ovarian cancer progression.”

Commenting on her death, a fan wrote, "Last time she posted online was in 2024 and she mentioned her mental health was better. She passed at 36."

"Just turned 36 a week ago… so heartbreaking," said another.

One fan said, "The news has been full of famous folks passing at younger ages lately. RIP, hope the best for her family".

"The post said sudden death. She was off of social media though for a while so maybe they just didn’t want to announce any diagnosis if there was one," noted another.
