Jackie Stallone has died aged 98.
The head of the Stallone family is believed to have died from unknown causes, according to TMZ.
Jackie, the mother of Sylvester and Frank Stallone and Toni D'Alto was famed for her bold personality over her glittering career.
The self-proclaimed "Queen of Hollywood" became a household name after becoming a female wrestling promoter on the TV show, G.L.O.W which aired for five years in the 1980s.
Jackie, born Jacqueline Frances, was most known in the UK for her appearance on Celebrity Big Brother back in 2005.
The outspoken star was introduced as the series "surprise" housemate.
Her appearance went down in reality television history following her clash with ex-daughter-in-law Brigitte Nielson, who she had not seen since 1987.
The pair famously clashed both in the Big Brother house and outside, with Jackie's entry uttering the words: "yeah, Jackie" becoming an iconic phrase.
However, her appearance on the show was shortlived and she was evicted by the public just four days into her stint in the Borehamwood house.
Despite nearing 100-years-old, Jackie showed no signs of slowing down - often documenting her weight lifting exercises to her social media channels.
Aged just 15, Jackie ran away from home and worked as an aerialist on Baily's The Greatest Show on Earth.
She later went on to become the first woman to have a regular exercise and weightlifting programme aired on primetime TV.
Since the news of her passing, fans have flooded social media with messages of condolences.
One fan wrote: "Oh my heart broke hearing of the passing of #JackieStallone. 98 years young and was still doing pilates."
While a second added: "Rest in peace Jackie Stallone. She was a delight on Celebrity Big Brother."
"RIP Jackie Stallone the mother of Sylvester Stallone, for those who were wrestling fans back in the 80's she was the manager of the good girls on GLOW," tweeted a third.
"Jackie Stallone, you will be missed," said a fourth.
The star had been married three times, firstly to Frank Stallone Sr, who she shares her two sons with, Antony Filiti who she shared daughter Toni with and Stephen Levine, who she married in 1998.
Jackie is survived by husband Stephen, her two sons, Sylvester and Frank as well as her seven grandchildren.
