Reality star Billie, who is expecting her first child with fiancé Greg Shepherd, talked about the scan which viewers saw on Sunday's episode of the reality show.
Speaking to TOWIE Insider, Billie said: "When I had the baby scan and I saw the 4D pictures, it was amazing and so much more clear than what I had imagined.
"I thought because I'm only 21 weeks I didn't think it was going to be as clear and the baby was going to be as formed as what it was. But it was amazing. It was quite emotional. I got a bit choked up but I stopped myself from crying."
Minnies Boutique owner Billie announced her engagement to Greg last week and confirmed that the couple are expecting a baby girl.
In the show, viewers saw Billie and Greg break their happy engagement news at a party attended by all their friends held at Nu Bar in Loughton, Essex.
The loved-up couple also revealed their baby's sex by slicing into the cake to reveal a pink sponge.
Speaking of baby names, Billie said that the couple are yet to decide: "We have got a couple of names in mind. We're not set on anything yet but we're going to get our top three names and then, when we see the baby, whatever comes to my head is what she'll be called."
Soon-to-be mum Billie also spoke about the excitement of her co-stars: "Being the first TOWIE mum is amazing but never in a million years would I have thought it would be me," she explained. "I thought it would be Gemma or someone like that.
"All the other girls are really excited as well to share the experience with me and do all the things like baby yoga and pram shopping so hopefully, you never know, there could be another TOWIE mum soon after me!"
