Chezzi - who is married to TV host Grant Denyer - suffers from Hyperemesis Gravidarum (AKA extreme morning sickness) and always makes sure to keep it real about the highs and lows of motherhood.
"Here’s a sexy snapshot of me struggling with my Hyperemesis gravidarum today," she penned earlier in the week. "I don’t want pity. I am surviving. I know this path well - It’s my 3rd HG pregnancy. I don’t need help - I’ve got my husband & family looking after me. But I’m posting this to contrast the smiling happy photos I’ve shared recently to encourage those going through it. that it is difficult and awful. And I see you and I hear and feel what you’re going through. Know you’re not alone."
Many of her 58.7k followers thanked her for her honesty and shared their own experiences with pregnancy.
"Thank you so much for being so authentic💕" one wrote. "Oh wow you are an actual superwoman xo both mine were HG pregnancies too xo sending you virtual zofran, laxatives and love xoxo," added another.
Just last month, her husband posted a stunning black-and-white of Chezzi, captioning it with a loving tribute to his family and unborn child.
"Such a glorious glow. Can’t wait to meet the spectacular little person growing inside," he penned.
"The house is abuzz, the kids are so excited and the love a new baby brings into the home is unparalleled. It’s such a special time. I already have two of the most incredibly sweet, funny, smart, compassionate and adventurous little ones in my life, I can’t imagine what joy a third will bring."
Grant added: "Yeah no doubt it’s going to be hard at times, 2 parents and 3 kids means one’s always on the loose but I’m sure Sailor is going to be a stunning big sister. She’s a total sweetheart and a real nurturer. Scout will no doubt teach no.3 now to kick-flip a skateboard and jump a mini-bike."
"Between all 4 of us, I’m sure no.3 will arrive to the warmest of open arms, and home that feels safe, warm and full of love. I just can’t wait to meet you xox."
“We’re just about halfway and at the same time we decided that we would do a renovation of our house – we haven’t even looked at baby stuff yet. And I gave all my stuff away, so we’re very behind,” Chezzi, who is due in March 2021, revealed.
Grant however joked: “I’ve been out on the Janome overlocker just knocking up baby suits.”
The Family Feud host and his wife announced their pregnancy news back in August with an adorable video on Instagram that featured their daughters Sailor and Scout.
"We have some exciting news..... coming 1 March 2021," Grant and Chezzi both captioned the video, which shows their two girls sitting at a table with a toy doll.
"So, we have some news. Our mum is pregnant! And mum's really sick. And she's been resting for days," the girls explained.
Grant previously spoke to TV WEEK about his determination to be present as his children grow up.
"My greatest concern is not being able to observe every single waking moment with those growing little monsters," he explained to the publication.
"Time is going so fast, and they're evolving so quickly in front of my eyes. I don't want to miss a thing – and as a parent, my greatest paranoia is, 'Am I focusing on work too much?'"
