Mother of disgraced Melbourne wellness blogger Belle Gibson says her daughter not only lied about having cancer, but she also made up her claims of having an underprivileged childhood.

Belle’s 54-year-old mother Natalie Del-Ballo has come forward for the first time to set the record straight about her estranged daughter in an interview with The Weekly.

Gibson, an alternative health advocate, admitted last month to lying about her fake brain cancer diagnosis and persona that help turn her into thriving wellness entrepreneur, with her own cookbook and The Whole Pantry app.

Later she explained that she may have lied because of her underprivileged childhood, a time where she claimed to have worked from the age of five as the primary carer of a mother with Multiple Sclerosis and a brother with autism.

But according to her mother Natalie, that’s a “lot of rubbish”.

“Her brother is not autistic and she’s barely done a minute’s housework in her life,” Ballo said.

“I’ve practically worked myself into an early grave to give that girl everything she wanted in life.

“I just couldn’t sit by and let her say these things about her family.”

However, Natalie did admit Belle’s account was partly true, confirming that she does have multiple sclerosis.

Gibson’s 26-year-old big brother Nick confirmed what she said about him having autism was a lie.

“I’m disgusted with Belle and what she’s done,” Nick told The Weekly.

“It’s about attention, she’s always been like this.”

Gibson’s family had no idea about the cancer lies until the news broke of her public confession and were shocked to find out about what the 23-year-old had been doing.

Her mother was particularly disturbed, saying her daughter should apologise for the pain she caused.

“I read the story [Belle’s exclusive interview with The Weekly] and I was in a state of shock,” Ms Del-Ballo said.

“I couldn’t believe what she had done and I felt like I had been erased from her life — dead.”
