Danielle and Lockie broke up during the cast holiday to Marbella, where she accused Lockie of treating her badly over the last few months, unaware he was hoping to propose in Spain.
Last week, Mario asked Lockie if he was going to join him on a club night on Saturday, tweeting: "So @JamesLock__ are you ready for @GalleryClub_ Saturday?? No engagement party?"
Lockie replied: "Haha.... Cheers mate! See u there @Mario_Falcone @GalleryClub_."
Having seen the tweet a few days later, Danielle made it known to both Lockie and Mario that she felt it was insensitive.
She tweeted on Saturday: "@JamesLock__ @Mario_Falcone Nice to see u both see the funny side in our NO engagement and what we are going through. Have fun tonight."
However, Mario insisted his tweet was misinterpreted, and he was in no way making fun of their break up: "@Daniarmstrong88 @JamesLock__ I would say you have misinterpreted the tweet but [if] it's upset you I apologise."
In last night's episode of the reality show, Danielle and Lockie officially split for good, with Lockie moving out of their flat in Essex.
After the show, Danielle shared a photo of herself and Lockie together, with the caption: "You will always be my best friend and have a special place in my heart."
