Simone Holtznagel treats week old daughter Gia to lunch

Simone Holtznagel is basking in life as a new mum. 

The model welcomed her first child, a baby girl called Gia, with boyfriend Jono Castano on Easter Sunday.

And seven days later, the 30-year-old took her week-old newborn to a glamorous lunch date at Sydney celebrity hotspot Totti’s in Bondi. 

The Italian eatery is a favourite with the A-list and Simone is starting her baby girl on the good life early.  

In photos posted to Instagram Stories, Simone declared it was ‘Gia’s first Totti’s trip’ and shared an image of a cocktail alongside her pram. 

She also shared an image of her order of delicious food, and indicated that new father Jono also came along.    

Just a week after the happy arrival, Simone also announced she is back in her old jeans. 

Posting to Instagram Stories, the former Playboy model shared a mirror selfie as she cradled Gia while posing in a pair of loose-fitting blue jeans and a matching denim jacket. 

Looking every inch the yummy mummy, Simone completed her look with a pair of gold earrings, silver bracelets and a full face of makeup. 

‘Feels so good to wear jeans again [laughing emoji],’ the blonde captioned the photo.

Hours earlier, Simone shared a heartwarming close-up video of Gia smiling in her cot as she was tickled by her doting mother.  

Simone announced last week that she had given birth on Easter Sunday, sharing some adorable photos of her newborn to Instagram. 

‘On Sunday March 31st we welcomed our healthy, baby girl Gia Holtznagel Castano into the world,’ she wrote in the caption.

‘We are totally and completely in love with her and enjoying these special moments as a family of three.’ 

In one sweet photo, Simone held her newborn daughter while lying in a hospital bed as Jono sat alongside her. 

Simone announced that she and boyfriend Jono were expecting their first child together in October and later confirmed they were having a baby girl.
