‘Words will never describe or could ever describe my love for you. Our little family of four. Two under two…. What a journey.

‘Delivered at 38 weeks and although you had a high chance of being growth restricted due to low PAPP-A, you already proved your strength. My champion.’

The couple welcomed their first child, a daughter, together back in November 2023.

Commemorating the occasion, Lizzie posted some never before seen photos of herself in the maternity ward before she welcomed the little one.

Completely makeup free, Lizzie glowed as she posed up in a blue hospital gown.

In the caption, the new mother described the moment as ‘the happiest day in her life’.

‘The day I was able to hold my dream girl in my arms. Right on 41 weeks. So much for potentially coming early. My gosh, she is everything and more,’ she said.

The reality star announced the joyous arrival via Instagram by sharing two photos of herself and Alexander cuddling their bundle of joy in hospital.

‘8.11.23. I have never been happier. My everything. A love so strong. Pure bliss,’ she captioned the heartwarming images.

Lizzie also shared a second close-up photo of herself cradling her newborn, writing: ‘She is absolute perfection, everything to me.’

Lizzie was famously fat-shamed by Sam Ball on the 2019 season of Married At First Sight
