The girls made a seriously glamorous trio as they posed up a storm at the Great Gatsby themed party.
Megan looked stunning in a floor-length embellished gown draped with pearls, meanwhile Chloe wore a white dress with fringed tassels and Courtney jazzed things up with a midnight blue playsuit.
It was only confirmed on Thursday that Megan would be joining the show for the 200th episode this Sunday. Courtney and Chloe, however, are new cast members having joined the show at the start of series 17 in February,
Courtney in particular has had a difficult start to the series as she hasn't made the best impression with some of the girls.
Courtney clashed with Danielle Armstrong after taking an interest in her ex James 'Lockie' Lock. And, rumours have been circulating around Essex that Courtney and Lockie slept together, something which they have both strenuously denied.
The last episode saw Courtney admit to Chloe that she was finding the tension too much to handle.
"When I walk into a room and Danielle is there I feel really awkward," she said. "I have tried hard with these girls. They've tweeted horrible stuff about me and don't really know me. I feel like they've chosen not to like me for no reason."
Danielle, who had called her a "green-eyed monster" during the episode, said in a Snapchat video: "I come across as a bit of a bitch, I'm dreading tonight, please don't judge me... Just try and understand working with your ex is quite challenging and when girls talk about him, you just don't want to know about that sh*t."
While Megan is close with Courtney, she's also really good friends with Danielle, so perhaps the pair will be able to make up and move on?!
