The former TOWIE star shared the gender reveal with OK! magazine, telling interviewers: 'Me, Brad, my mum and Auntie Karen were all there for the scan. I was in so much shock I walked out of the room and didn't even say goodbye to the nurse. Brad is very quiet so he wouldn't get emotional, but we were all so excited. I'm having a mini Amy!'
She added that the baby's sex came as as surprise: 'I was just so convinced that I was having a boy. Brad thought it would be a girl from the start and he was right. But I've wanted a baby for so long. I'd dream about it and talk about it all the time. I feel so lucky.'
Amy has shared pictures from her baby shower after confirming that the baby she is carrying is a girl
Amy originally revealed her pregnancy to the same title, revealing that she was 'shocked but happy' at the news, especially as she had previously thought that she couldn't get pregnant, and even showed off her blossoming baby bump.
The former TOWIE star was over the moon to be expecting, as she and boyfriend Bradley had been wanting a child together for a while.
'We wanted one (a baby) before Bradley went to prison but it didn't happen. I didn't think I could get pregnant,' she said in the interview. 'We'd been together for nine months and I came off the pill in the summer and I thought it might take me ages.
'I was taking folic acid but it didn't happen. I was really panicking. I went online to find out why and it was the worst thing I could have done. I got so stressed out about it that I was drinking. Brad told me off for it but I couldn't help it.'
Amy also spoke about how desperate the pair have been to become a family, especially as Bradley already has a daughter from a previous relationship, Lexie.
'I love kids, especially because Bradley has Lexi, and spending time with her made me want a baby more. I have a big family so I love having my nieces and nephews around,' Amy said.
'We wanted kids together soon after we met.'
Amy broadcast the happy news on Twitter, as she tweeted OK!'s article with the caption 'We are so excited...xx'

Amy was met with many congratulatory comments, with followers sending their best wishes to the couple.
'Oh my gosh! Congratulations to you & Brad! You'll be a brilliant mum' wrote one follower.
'YAY congratulations @MissAmyChilds on the baby news. Going to be a brilliant mother. Can't wait to see baby photos. Enjoy every moment' wrote another follower in a tweet which Amy retweeted.
Amy and Bradley met in a pub in Essex two years ago, but their relationship became complicated last year when Bradley was sentenced to 16 months in prison for being in possession of stolen goods.
After Amy publicly vowed to never get back together with him, the pair ended up dating once again after Bradley served five months of his sentence for good behaviour.
