The social media influencer, 23, is expecting a baby girl with her boyfriend Tommy Fury.
To celebrate reaching the nine-month mark, the former Love Island contestant filmed a video in her glamorous bathroom to speak about her bump.
Wearing a black tank top and green tracksuit bottoms, Molly-Mae admitted: "I definitely went on a journey with my bump from being not very confident at all to like, quite confident in it."
She then revealed a comment made to her by builders working on the home of her friend and manager Francesca 'Fran' Britton.
"They were like, 'Are you carrying twins?' And I was like, 'No I'm not!'" the shocked reality star revealed. She added that she reacted by saying: "Excuse me!" during the interaction.
While caressing her bump, she explained: "To me it looks like how I would expect my bump to look full term. If anything, I thought it would look a little bit bigger. But yeah, this is me."
Last week, the PrettyLittleThing creative director shared that she never feels lonely during her 'special' pregnancy in an intimate vlog.
In the 30-minute video, the mum-to-be explained that she was having a really easy time of things, and that she feels as though she was always ready to be a mum.
In an emotional moment, Molly-Mae said: "When you're pregnant... this is going to sound so cringey. When you're pregnant, you're never lonely.
"Like, literally, you never feel alone. Why am I getting choked up saying that? What the hell?"
Composing herself, she added: "You never feel... what the hell? You never feel lonely.
"You're always with someone. And that is such a special feeling.
"Like, when I'm at the house and I'm home alone or Tommy's nipped out, I never, ever feel lonely or by myself because you're not.
"You've got a little person inside you and are constantly in the company of someone else."
Molly-Mae has kept fans up to date with her pregnancy after announcing that she's expecting her first child in September last year. She shared that she has enjoyed a really 'smooth' pregnancy.
"I don't want to go on about it too much, the fact that I've had such an incredible smooth journey with my pregnancy because I know that's not the case for a lot of women through pregnancy," she shared.
"But the only way I can describe it is that I feel like my body was literally made to grow a child, I have never felt more natural.
"I can't explain it, I feel like my body was made to do this and was built to grow a child - it's been that smooth and amazing."
