Meet the secret Holtznagel sister: Justin Hemmes’ girlfriend Madeline and model Simone pose with their sibling Anna for rare photo as she enjoys a quiet life away from spotlight

Madeline Holtznagel and her sister Simone have made a name for themselves as two of Australia’s most successful models.

But their oldest sister Anna, 33, enjoys a quiet life away from the spotlight.

However the siblings posed for a rare photo together last month at Madeline’s lavish baby shower.

The expecting mother, 28, is set to welcome her first child, a son, with billionaire pub baron Justin Hemmes.

The sisters wore matching white dresses as they looked lovingly at heavily pregnant Madeline while posing with their mother Margaret.

Also in the sweet family photo was Anna’s young daughter.

Simone, 31, has also been embracing motherhood since welcoming her daughter Gia in March last year with ex partner Jono Castano.

Their sister Madeline is set to welcome her first child with Justin and hosted a baby shower at the entrepreneur’s $100million Vaucluse mansion.

She has since admitted she is happy she will give birth to a son, because she wanted a ‘new journey’ with her partner, who already shares two daughters with his ex Kate Fowler.

‘I always thought I was going to have a boy. I knew I was going to be a boy mum,’ she told Stellar Magazine last month.

‘Justin has two beautiful little girls, so having a boy, it’s like a whole new journey together.

‘[The baby] is going to be his little best mate.’

Madeline broke her silence on her pregnancy as she showed off her baby bump in Stellar and revealed she is having a baby boy.

The mum-to-be said she has kept the pregnancy process to herself but was now ready to share her journey.

‘I keep a lot of my life private and I don’t share a lot online anyway, so [being pregnant] wasn’t really something that I was going to share online,’ she said.

‘I haven’t posted about it and it’s been nice to have some quiet time off Instagram.

‘But obviously because I am in the public eye and we do get photographed quite a lot, I think now I’m at this point in my pregnancy where it’s nice for me to be able to share some nice photos.’
