Hitting a rocky patch, Fran revealed that she had found naked pictures of another girl on Diag's phone during last night's TOWIE episode.
But, dressing up for the show's Mythical Creatures Halloween party as the show aired, Fran made sure her boyfriend's eyes wouldn't be straying elsewhere!
In true Mean Girls style, Fran decided to ditch the traditional scary dress and sass things up with her teeny 'fallen angel' costume.
Donning striped suspenders, Fran wore a fitted black corset with a short feather skirt.
Finishing off her sexy outfit, the reality star opted for big bouncy curls, seriously dark smoky eyes and a bold red lipstick on her lips.
Alongside a snap of herself in her getup, Fran tweeted: "Halloween is the one night a year when girls can dress like a total sl*t and no other girls can say anything about it."
Oh, Regina George would be proud!
Fran's Halloween sexy fancy dress-up comes after she and her boyfriend Diags were seen coming to blows over naked pictures last night.
Not wanting to split from his girlfriend, Diags explained the photos were from two years ago - before he had even met Fran. Reassuring her he would never cheat on her, Diags told Fran she needed to trust him as he is not going to hurt her like he knows people have done in the past.
Diags' girlfriend has since admitted she has trust issues when it comes to relationships, but speaking out after the naked picture shock, Fran suggested she and Diags could still work things out.
Tweeting she still "loves her James", Fran said she has been left cold-hearted by people she trusted in the past.
Fran also told her followers she knows she has to work on her issues for the sake of their relationship. Come on, guys, you can get through this!
