Married At First Sight Australia star Martha Kalifatidis has admitted she felt "devastated" as she discovered she was having a baby girl.
Martha is expecting her first child with Michael Brunelli, whom she met on the TV experiment.
The mum-to-be was expecting to be told she was having a girl – and wasn't pleased when she found out they were having a son.
Speaking on KIIS FM's Will & Woody, pregnant Martha confessed: "I'll be so honest with you guys, at the beginning I was devastated.
"I was so upset, it took me a few days to come to terms with it."
One of the show's hosts then joked: "We'll make sure to send your son this audio when he's finally born as well," before the pair burst out laughing.
Martha also explained how she was "100% sure" she was having a girl. She added: " had only opened girl clothing tabs on my phone, I was so convinced".
The reality star said: "There was no chance in my mind it was going to be a boy, I had planned my whole life for this girl."
Martha shared a video of her finding out she was expecting a baby boy. The montage clip shows Martha throughout her pregnancy – including a moment where the pair are trying to guess the sex of the baby while at an ultrasound scan.
The video also saw Martha opening a ring box to discover if she's having a boy or girl. She can be heard saying in the video: "I think it's a boy," before snapping the box open and shut and covering her mouth with her hand.
Martha can then be heard saying: "I don't wanna know if it is."
As the montage video plays clips from Martha's pregnancy, she can be heard opening something before saying: "Oh my god it's a boy!," while her family cheers.
The MAFS star posted the video on her Instagram page and wrote in the caption: "Oh boy do we have news..."
Fans congratulated the couple in the comments as one wrote: "No one will ever love you quite like your son. It’s so special. Congratulations Mumma xx".
Another added: " Yay, a beautiful boy xxx," while another penned: "Congrats" followed by a trio of crying emojis and a blue heart emoji.
Martha and Michael, who met on the TV show and got engaged last year, announced they were expecting a child in September after being silent on social media for some time.
Michael spoke on behalf of the couple in the clip as he said: "It's been a minute since we've been online. So we wanted to explain our situation and make a little bit of an announcement.
"And that is that Martha is pregnant."
Martha added: "It hasn't been this exciting, wonderful time for us. I don't wanna sound like I'm complaining we are so excited, we are so happy. It was a complete surprise but at 5 weeks I was diagnosed with hyperemesis gravidarum, which is basically is severe, chronic nausea and vomiting with no relief.
"It's like 24/7, I literally didn't get out of bed for two months I was so sick. I couldn't eat or drink anything, there were days when I didn't even get up to pee."
