But New Idea can reveal that Victorian mum Fiona is hiding a shocking secret.
She has a 19-year-old son!
While viewers were introduced to Bannan, 14, and Keenan, 11, on a recent episode of the show, she refrained from disclosing the identity of the mystery member of her family.
‘I was married for nearly 20 years and we had three children together,’ she tells New Idea.
But that’s not the only thing fans might be surprised to learn about the 44-year-old.
Thanks to her eldest son, she’s also a nanna!
‘I have a granddaughter,’ she explains.
‘She’s amazing, she’s beautiful.’
The controversial reality TV star has previously opened up about the financial pressure she feels as a young single mum of three.
Speaking to News.com.au she confesses: “I almost lost the house last year but family stepped in to help me out.”
