The woman who created one of the best 'Big Brother' entrances ever, has passed away.

Jackie Stallone, the mother of Hollywood actor Sylvester Stallone and astrologist to the stars, died in her sleep on Monday at the age of 98.

As well as being the mother to her three actor sons, Sylvester, Frank and Toni D’Alto, Jackie became well-known in the '90s for a series of astrology books and her own psychic hotline.

She also appeared in the 1980s wrestling program 'G.L.O.W.: Gorgeous Ladies of Wrestling', which you'll know for its Netflix remake.

One of her most well-known appearances, however, was when she crashed the party of series three of 'Celebrity Big Brother' in 2005. Her former daughter-in-law Brigitte Nielsen, who the astrologist didn't get along with, was already in the house. This led to one of the best entrances in the show's history.

Jackie's son Frank, the younger brother to Sylvester, made the announcement on Facebook Monday night. He wrote on social media that his mother had died that morning: "She was a remarkable woman, working out every day, full of spunk and fearless.

"She died in her sleep as she had wished. It was hard not to like her, she was very eccentric and flamboyant person…She lived through prohibition, the depression and World War II. I would talk to her for hours about the 20s 30s and 40s. It was a history lesson. Her mind was as sharp as a razor till the day she died."

Here is that glorious moment of Jackie Stallone entering the 'Big Brother House', which we will never forget.
