Last night, Stephanie was shown chatting to Binky about her relationship drama with Alex Mytton while out for drinks with the heartbroken star and Louise Thompson.
"So do you want to be his girlfriend again?" Stephanie asked Binky. "Is it really worth it? I feel like you're just playing with fire. I don't think I could ever be with someone whose cheated on me ever again."
Following her comments, Stephanie received dozens of messages on Twitter accusing her of being a "hypocrite" following her recent trip to Venice with her ex-boyfriend Spencer Matthews.
During the holiday, Stephanie shared a drunken kiss with Spencer after he apologised for cheating on her last year and presented her with a peace offering - a Prada handbag.
Taking to Twitter last night, Stephanie insisted that her situation is not the same as Binky's and responded: "People calling me a hypocrite ... different situation, a kiss in Italy is not taking him back. duhhhhhhh #madeinchelsea."
Spotting her tweet, Binky replied: "@stephaniepratt was it just a kiss?" She then posted a funny face emojicon next to her message.
But it seems as though Stephanie didn't find her tweet funny. Appearing to raise the tension by dropping in the F-bomb, Stephanie shot back: "@BinkyFelstead errr ya! ask your friend who's bed she slept in that night... I woke up next to Lucy! #itwasjustaf***ingkiss!"

Binky then simply responded: "@stephaniepratt lol............" To which Stephanie said: "@BinkyFelstead you know the truth , don't be a b*tch."
It's hard to work out whether the girls really are hating on each other, as their tweets could also be read as banter. Whatever it is, their fans can't get enough of the drama.
"I'VE GOT MY POPCORN!! @stephaniepratt @BinkyFelstead," one tweeted.
