The former Farmer Wants A Wife star from the 2021 season previously revealed she was expecting a baby with Farmer Will Dwyer, despite not being one of the contestant's vying for his heart.
Will and Hayley struck up a romance once filming finished, with their fallout playing out publicly as her pregnancy was revealed.
"On the 2nd April I left his house thinking, 'I'm never coming back, I'm done.' The next morning, I found out I was 6 weeks pregnant. I was terrified to tell him," she said in a statement.
Of the baby news, Will shared his own statement on Instagram to say: "When the time comes, I will be the best Dad I can be."
Hayley had been one of Farmer Matt Trewin's contestants, with the pair remaining friends despite the fact he sent her home.
Despite the off-screen drama, Hayley shared with fans that she was looking forward to becoming a mum more than anything.
"I cannot wait to meet you!" she wrote of her bub as she celebrated her first week of maternity leave.
At 36 weeks, Hayley told her followers she wished she had shared more of the pregnancy journey.
"First trimester was a struggle with sickness, second trimester was amazing, third trimester has been a rollercoaster," she wrote on Instagram.
"I wish I shared more of my pregnancy but I’ve been feeling negative and didn’t want to sugar coat anything. I put on clothes and feel like a whale. I usually have a cry about it. My ankles swell up. I’m out of breath putting shoes on.
"I feel incompetent and I find it hard to process at 26 years old. But I am so grateful that I am growing a healthy little bubba. I hope to meet you sooner rather than later."
While she may have been feeling the all-too-relatable struggles of pregnancy, Hayley now seems happier than ever with the arrival of her beautiful baby girl Daisy. Congratulations to the new mum!
