The Made In Chelsea cast reacted with shock and tears when Binky Felstead revealed her baby news.
Scenes of Binky telling her pals on the show will air in the new E4 series later this year.
But Stephanie Pratt has spilled on what we can expect to see, recalling: "Once I got over the initial shock I cried! I'm so excited to watch that footage on the show."
She revealed: "Me, Louise, Rosie and Binky where meeting for dinner but Binky was running late. Rosie was annoyed because she said she'd been trying to see her for ages.
"Then she arrived and she told us and we were like 'What the f**k!" and JP told the boys at the same time!"
Stephanie added to this week's OK! magazine: "We're all going to be aunties. She will make an amazing mum. I don't think anyone has ever been more excited about a baby. It's really brought everyone together."
Binky announced that she and on/off boyfriend Josh Patterson (JP), who both appear on E4's MiC, were expecting a child together back in January.
She tweeted: "When you get the best surprise you never knew you always wanted ... There's a little 'buh' on the way 👶🏻❤️"
Speaking to Hello magazine, Binky candidly confessed: "My first reaction when I saw [the positive test], honestly? It was ‘S**t’.
“My heart stopped. I burst into tears.“
She explained: "Josh and I weren’t talking at the time and I was really overwhelmed.”
JP told the magazine in a joint interview with Binky: “Where we’re both being very mature is with the fact that you should never get back together just because there’s a baby in the picture.
“It has to be for the right reasons.
“We love each other a great deal and there’s no pressure – but you do have to take the past into consideration, where there have been a few hiccups. We’re just taking it very easy.”
Made In Chelsea's new series returns to E4 in March.
