Saying “better late than never,” Aaron is seen telling the cameras: “I’m not gonna lie it’s always good to see Marnie’s face!
Reunited with friends Chloe Ferry and Nathan Henry, Marnie admits she and Aaron are in a good place.
When Chloe asks how things are between the former couple, Marnie says: “Good! We’re getting on.”
Lewis Bloor’s ex then tells the camera: “It’s my first night out in France.
“I need to make sure I look super sexy. I just can’t wait to hit the town!
While Aaron adds: “I’m really happy that Marnie’s back whatever’s happened between us in the past we’re best mates and I don’t wanna lose that.”

As the gang hit the town, however, things quickly get messy.
Marnie, who gets progressively drunker throughout the night, starts arguing with Aaron before throwing a drink in his face.
“I dunno what’s got in to Marnie, I’ve never seen her this drunk in a long time!” says her cousin Sophie Kasei.
Aaron is then seen telling Geordie Shore: “Me and Marnie are getting on really well and the all of a sudden she starts kicking off at us!
“That girl is a f**king nutcase!”
Marnie tries to justify herself by insisting she has “underlying issues” stemming from her previous relationship with Aaron.

But her co-star Gaz isn’t having any of it, raging: “You managed to flirt with Aaron, stop him from pulling and you even threw a little swill in there as well.
“How the f**k did you manage to pull that off?”
He then tells Aaron: “She’s mugging you off mate! Big time!
“She’s in control; she’s running the show.”
