The tragic news comes after Jacqueline and her other half Dan recently moved into their new home with the couple’s two children Ella, six, and Mia, two.
The former The Only Way Is Essex star, Dan, also has a seven-year-old son Teddy from a previous relationship.
Jacqueline was crowned Queen of the Jungle during her stint on I’m A Celebrity in 2019.
The small-screen star was a regular on the BBC soap EastEnders for seven years until she quit in 2017.
