Her sister Amy welcomed her first child, daughter Aurora, last month.
And on Saturday, Tammy Hembrow doted on her newborn niece as she and Amy watched the sunrise at a Gold Coast beach.
The 26-year-old headed out at 5am with her family and shared online some sweet snaps of herself holding Aurora.

Tammy kept cosy on the outing in an oversized bright pink hoodie and pale pink track pants.
The blonde bombshell pulled her long locks into a neat high bun, still donning a full coverage foundation despite the early hour.
She cuddled with her one-month-old niece Aurora, who was bundled up in a blanket, brown knitted cap and a grey knitted cardigan.

Last month, Tammy shared a heartfelt congratulations to her older sister on Instagram, after she welcomed Aurora.
‘My big sis Amy Hembrow gave birth to the sweetest little baby girl,’ Tammy wrote.
In the photo, Tammy is seen lovingly holding the baby girl up to her chest.
‘Baby Aurora you are already so loved!’ Tammy wrote alongside the image, before adding: ‘I am in AWE of you Amy, you did it like a freaking BOSS!’

‘Completely natural just how you wanted. I’m so proud of you! Princess Aurora is absolutely perfect’.
In a post on Instagram Stories on Sunday meanwhile, Amy detailed her birthing experience and revealed why she chose a water birth.
‘I had a feeling that she would come early… I was laying in bed and at 1am, my water broke,’ the 29-year-old recounted.
Telling all: In a post on Instagram Stories on Sunday meanwhile, Amy detailed her birthing experience and revealed why she chose a water birth
‘I actually felt a pop, and I was like, “Oh, that’s weird,” and then I felt some water, and I was like, “Oh, I think my waters broke,” so I ran to the toilet, because I didn’t want to get water everywhere.
‘I yelled from the toilet out to Rory, I was like, “Babe, I think my water broke!” and he jumped out of bed like, “What?!”‘
Amy said she ‘wanted to labour at home for as long as I could before going to the hospital’, and she’d created a ‘preference sheet’ of what she wanted to happen.
Amy said she ‘chose not to know’ how dilated she was during the labour, because she didn’t want to get ‘disheartened’ if she still had a long way to go.
She said she was in the shower when she ‘transitioned into the final stretch’ of her labour, and was then ‘asked to get into the water bath’, where she listened to a playlist of Nick Cave songs and affirmations.
‘It was honestly such a surreal experience. At 1am, my water breaks, by 3.20pm, I’m bringing a baby home,’ she said.
