Simone Holtznagel is all smiles as she shares very sweet elevator selfie with eight-month-old daughter Gia

Simone Holtznagel looked every bit the doting new mom as she shared an adorable photo of her daughter Gia on Sunday.

The Australian model, 31, was all smiles as she took a lift selfie while cradling her giggling bundle of joy in one arm.

The blonde beauty posted the candid photo to Instagram and captioned the image with a simple “Say cheese,” alongside a laughing emoji and a cheese emoji.

The mother of one, who shares Gia with her ex Jono Castano, opted for a very fashionable but casual ensemble during her outing with the little one.

Wearing a white tank top and faded mom jeans, Simone hid her eyes behind designer sunglasses as she carried a brown woven bag on her shoulder.

Simone completed her look with a set of red nails and leopard print shoes as she juggled a can of Coke and baby Gia in one hand.

The socialite split from her former boyfriend, celebrity trainer Jono, 33, on Easter Sunday, just nine weeks after they welcomed their baby daughter Gia into the world.

Earlier this month, Simone hinted that she is really over her ex when she shared a telling message on her Instagram last Wednesday.

The blonde beauty shared a photo showing two cards from a pack of Beyond Words cards.

The card game contains 52 cards with inspiring aphorisms, accompanied by illustrations by artist See Aiche.

Simone’s photo showed one card face down, while another had a quote from an “unknown” source.

The quote read: ‘The best revenge is no revenge. Move on, be happy.”

The post appeared to be a pointed comment on her relationship with Jono, just months after their divorce.

Jono confirmed the news of their split to Ny Breaking Australia in July, and Simone has since said she is raising Gia alone.

She cryptically noted that she ‘couldn’t change’ the man she loved Stellar: ‘I wanted to be an example for my daughter; that’s something that has changed for me.

‘One day I thought, “What am I doing? This isn’t right.” And I would hate for her to ever be in this situation.”

She continued, “At the end of the day, you have to do what’s right for you.

“No matter how many promises or whatever people make, if they show you who they are, believe them. Because you can’t change people.’

Simone also said that she is content raising Gia alone and is confident she made the right choice.

“I’ve never been so sure of anything, and I know I can do it on my own,” she said.

‘It’s a shame that I have to do it largely alone, but I really couldn’t think of it any other way.

‘What I do just feels very good to me. The most important thing for me is that Gia is happy and healthy, and that I am happy too.’

Simone and Jono first started dating in 2022, months after Jono confirmed his split from his longtime partner Amy.

Celebrity personal trainers Jono and Amy were high school sweethearts but divorced in 2021 after 15 years together.

Simone confirmed she and Jono were expecting their first child last October and welcomed Gia on Easter Sunday, March 31.

Jono has since moved on with fashion designer Nilofar Khirzad.

The new couple went Instagram official with their relationship when Nilofar shared a photo of them sharing a kiss during a night out in Sydney’s eastern suburbs.

Jono sparked rumors that he was in a new relationship after he was spotted liking him in October and leaving very flirty comments on Nilofar’s Instagram posts.
