And it's fair to say the reaction is mixed.
In a trailer for this year's series, Binky is see sitting down with Louise, Rosie and Stephanie where she announces she's 18 weeks pregnant.
"WHAT?!" reacts Louise in the clip.
Meanwhile, baby daddy JP announces the news to the guys, leaving Jamie with his head in his hands.
The trailer also sees Binky and JP meet up to discuss the news.
She also chats to pal Ollie and admits: "I can't believe I'm going to have a baby!"
Binky first announced that she and on/off boyfriend Josh Patterson (JP) were expecting a child together back in January.
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.”
The new series of Made In Chelsea begins tonight on E4 at 9PM.
Away from Binky and JP's baby news, Sam goes for an interview with Tiff's father Clive.
But when the couple are at Mark Francis' Russian Ball, Tiff is confronted by someone who accuses her of hooking up with her boyfriend last year. Will Sam have Tiff's back? And Fred is trying to help Julius find romance... will he succeed?
