Taking to the photo-sharing app, Binky posted a picture of herself and Alex partying together. The pair appear in pretty good spirits and Binky had everyone taking after including the caption: "When the ex has done his hard grafting..."
Fans were quick to question exactly what Binky had meant by that, with many beginning to speculate whether she and Alex could be getting back together.
One fan commented: "Omg!!!!!!!!!! I hope they get back together! This has made my morning." Another said: "Omg is this what I think it is?!"
Others weren't so keen on the idea of Binky and Alex rekindling things, with many pointing out that their relationship hadn't exactly been ideal. MIC fans will remember that Binky and Alex's relationship broke down, after he confessed to cheating on her multiple times.
"She better not be back with him," said one follower. While plenty more admitted they are pretty confused over Binky's post.
Others suggested that there is no romance involved and gave their own theories decoding Binky's caption. One fan said: "I think this photo and caption is saying after Alex has done his dj set (work) then it's time to party."
Another added: "I think she means his done enough for them to be friends again..."
Binky and Alex split back in 2014, and since then, the pair have both gone on to have other relationships.
While Binky found love with her co-star Josh JP Patterson, Alex had dated Nicola Hughes - although both have now split from their partners.
Viewers saw JP end his relationship with Binky, after hearing she'd had a big night out and later learning she had kissed somebody else. Alex, meanwhile, revealed he and Nicole while appearing on Made In Chelsea's South of France spinoff.
He revealed he had actually ended their relationship via text, after the pair hit a rocky patch.
Alex said: "We broke up. I basically messaged Nicola the other day and said, 'This is the hardest thing in the world, but it's done.'"
Nicola has since ruled out a reunion with Alex, she claimed: "I would never lower myself to getting back with him. I hope he finds whoever makes him happy. I thought I was pretty good, but obviously not."
