Lockie and Danielle split last year but had recently rekindled their friendship, although that appeared to come to a head last night.
The exes met for coffee which turned into a row when Lockie told Danielle to stop interfering in Jake Hall and Chloe Lewis' relationship, and to stop comparing them to him and Danielle.
It got a bit heated and Lockie stormed off.
When Danielle recounted the story to the girls later on, Chloe commented: "I don't get it because I'm actually really disappointed in him. He has this whole thing going on with the not drinking, everyone loving him, doing really well.
"Me and you both know he's asked you to go on holiday, out for dinner, then he's doing all that. It's like he wants to have a secret relationship with you but not tell everyone."
Billie Faiers chipped in: "He's trying to convince himself you really want him back…"
"Well he's convinced the whole of Essex if that's the case," added Chloe. "And it's about time you open your mouth, Dan."
Danielle said she'd done just that – kind of. She didn't open her mouth but she did block Lockie across all social media and said she would tell the boys she didn't want to hear anything about him anymore.
