Jacqueline Jossa is said to be throwing herself into I'm A Celebrity...Get Me Out Of Here! in honour of her two late baby brothers.
Jacqueline's siblings both tragically died from Sudden Infant Death Syndrome (SIDS) before she was born and, together with her sister Katrina, she has raised thousands of pounds for charity in their memory.
The former EastEnders actress has two children of her own and friends have said she "seizes the day" because of her family's sad past.
A source told The Mirror: "It makes Jacqueline even more grateful for her own children and also the need to seize the day and appreciate life.
"She has been working hard and earning money for her family since she was 17 so it is no surprise for them to see how committed she is to not giving up in the jungle."
It makes Jacqueline even more grateful for her own children and also the need to seize the day and appreciate life.
Jacqueline is not thought to have opened up to her fellow I'm A Celeb camp mates about the double tragedy, but she has spoken in the past about her brothers.
In March last year, her older sister Katrina took part in the London Marathon to raise money for The Lullaby Trust.
The charity supports families affected by SIDS and raises awareness of the syndrome.
Katrina wrote on her GoFundMe page: "I personally lost two baby brothers, one due to cot death and the other was put down to cot death although he died in hospital due to an illness caused by lack of oxygen at birth.
"I was a young child at the time of these deaths. The devastation on my family has been clear to see and I can't think of any challenge bigger or more fitting to show my love for the charity and my support to my family in moving forward."
Jacqueline later spoke to the Belfast Telegraph about her family's tragic loss, admitting that it made her worry more about her two daughters; Ella, now four, and 18-month-old Mia.
Pregnant with Mia at the time, she said: "My mum sadly lost two babies through cot death before I was born.
"Although there’s no apparent hereditary link, it does make you a bit more nervous - but again, the midwives have been reassuring."
