Aussie Supercars champion Chaz Mostert and his partner reveal incredible news a year after suffering stillbirth heartbreak

Supercars fan favourite Chaz Mostert and his partner Riarne Marwood have celebrated the safe arrival of baby Everly, a year after suffering heartbreak when their first child was stillborn.

The couple lost their daughter - Hazel Lola Mostert - 22 weeks into pregnancy, after a routine scan found an issue with the baby's heart.

The couple were engaged shortly after the tragic event and announced they were again pregnant in November.

Everly arrived on Tuesday, and both parents couldn't be happier.

'We are so in love with our precious little girl,' Riarne posted on Instagram.

'She is a dream come true.'

The post received a flood of well-wishes and congratulations from fans and fellow drivers.

'Congratulations. Super cute,' wrote Dave Reynolds.

'She is so beautiful you guys, a heartfelt congratulations to you and Chaz,' Will Davison wrote.

'She's gorgeous! Congratulations guys,' replied Madeline Stewart.

In June, Riarne revealed that Chaz proposed to her on a sunset walk five days after the heartbreaking end to her pregnancy in 2023.

'The love of my life got down on one knee and asked me to marry him. I've never been so sure of anything in my life than saying yes to spending my forever with you Chaz,' Riarne posted to social media.

'As the sun disappeared on the day we last held and said goodbye to our precious daughter, you filled my heavy heart with an entirely new depth of love.

'We are bonded in ways I never knew were possible and I'm forever grateful to have you by my side, through the good days and the bad.

'You are my everything, my soulmate, my love and my light. I can't wait to be your wife and spend the rest of my life with you.'
