Jackie Stallone, famed astrologer, reality television star and mother of acting legend Sylvester Stallone and singer Frank Stallone, has reportedly died at the age of 98.

According to reports from TMZ, Jackie, who often called herself Mamma Rambo, Mamma Stallone and Mamma Rocky, passed away – though they added that “the exact circumstances surrounding her death are still unclear.”

Jackie had a wide-ranging career, which included kickstarting the original Glow series, as well working in astrology and appearing on UK’s Celebrity Big Brother in 2005. More recently, however, she amassed a dedicated fanbase on Instagram where she described herself as “98 years young” and posted countless photographs of her beloved sons as well as her regular fitness routines, which lead to her adoring sons dubbing her the #QueenOfInstagram.

“I’m staying fit, I am studying the accordion daily,” she wrote on Instagram recently. “I think I know as much as my teacher does.”

Jackie was married three times, with her first husband, Frank Stallone Sr, being father of her two sons. She married Frank in 1945 before divorcing him in 1957.

In 1959, Jackie married Anthony Filiti, who is the father of her late daughter, Toni D’Alto.

And then, in 1998, she married Stephen Levine, who she would remain with until her death.

It’s the latest in a string of losses for the Stallone family, with Jackie’s daughter – Sylvester and Frank’s half-sister Toni D’Alto – dying in 2012 at the age of 48 from lung cancer, and Sylvester’s son Sage Moonblood Stallone passing away just one more earlier from a heart attack at the age of 36.

Jackie expressed her grief at the time, saying: “I saw my daughter die a day at a time of lung cancer, lying there, upstairs. I have on my counter with her ashes in an urn. Every day I couldn’t wait to go to bed at night and yet I hated to get up every morning because I knew what I was going to face, nothing was going to be any good. To have Toni Ann here and then have Sage die — it was just too much.”

Sly also revealed his heartbreak over losing his son so young, saying at the time: “I am imploring people to respect my wonderfully talented son’s memory and feel compassion for his loving mother, Sasha,” Stallone wrote in a statement to CNN, adding, “because this agonising loss will be felt for the rest of our lives.”
