Posting a video of the scan on her Instagram page, Stephanie - who is pregnant with a boy - admits to being nervous at the start before she breaks into a huge grin as the baby's heartbeat is clearly audible.
"I am so SOOOO UNBELIEVABLY IN LOVE WITH YOUUUU!!!!!!! I freaking love you my beautiful boy!!!!!!!" she wrote beside the video.
"Mummy's nervous face at the beginning hehe. I can't believe we're nearly there. We have done it baby!!! I've loved watching you grow and seeing and hearing you, every appointment. You are my entire world.
"Words will never describe how much I love you. We have been through so much, and look at us. Strong healthy and so happy! We have everything, family, our new home, just perfect. You are the reason to my life. I love youxxxxx love mummy xxxx [sic]"
This happy and momentous occasion comes after what's been a tough old pregnancy. The difficulties started when Steph, 23, split from her Celebrity Big Brother co-star in May. Although he initially denied the baby is his, Irish model Jeremy has since offered to do a DNA test once he is born.
Appearing on Loose Women last month she admitted that, after learning she was pregnant and splitting from Jeremy, she fell into an extremely low period in her life.
"It's been so difficult. At the time [of discovering she was pregnant] I was really really down and obviously in a toxic relationship and - me and my Mum were saying the other day - I honestly wouldn't have been here if it wasn't for the baby, honestly. My Mum even said the," she confessed.
"I was so down... I didn't see a way out, I was at a dead end and everything that I thought I was, I was portrayed in a different light. I was trying to block it out any way I could. Then I found out I was pregnant and I thought, 'That's it, I'm over.' I was just so lost.
She also suffered a pregnancy scare last month when she awoke into the middle of the night with agonising pains in her stomach and thought she was early labour. She was rushed into hospital but fortunately it turned out to be a false alarm and, happily, things have been steadily improving for Steph ever since.
Admitting on Loose Women, she went on to say: "Actually this baby has saved me."
There's even some speculation that Stephanie may have a new man in her life. Recent photos posted to her Instagram page show a mystery man's hand together with some rather smitten captions, but Steph is keeping us all guessing.
Writing in her OK column, she said: "I haven't said yes or no to whether I've got a boyfriend or not. What I will say though, is just because I'm pregnant, it doesn't mean I can't look for love. If I meet the right person, it won't stop me."
