The gang gather to celebrate Essex with a 1920s Great Gatsby themed party thrown by the original golden couple, childhood sweethearts James 'Arg' Argent and Lydia Bright.
But there's a surprise in store for all when Pete Wicks brings along his mystery date to the celebrations... Ex On The Beach and Celebrity Big Brother star Megan!
Of course, we don't think it'll be too much of a surprise for Courtney Green and Chloe Meadows to see Megan, as the three girls are all best friends.
Despite Megan's surprise arrival, it's not long before an argument erupts as Megan is immediately thrown into the middle of the ongoing drama between Courtney and Danielle Armstrong.
In recent episodes, Courtney and Danielle haven't seen eye-to-eye, with the pair clashing after Courtney took an interest in Danni's ex boyfriend James 'Lockie' Lock.
As Megan joins her BFFs Courtney and Chloe at the celebrations, Danni - who is also friends with Megan - soon approaches the trio with support from Georgia Kousoulou.
However, as fiery Megan steps in to defend Courtney, Chloe Sims overhears from afar and takes great offence to what she's heard.
Cue the drama!
Heated words are exchanged from the girls from both sides of the table as Chloe S squares up to Megan, Courtney and Chloe M.
Do we have another Essex feud on our hands?
The morning after all the drama, Danni and Courtney finally find themselves alone together. Will they be able to clear the air once and for all?
As for Chloe S, she meets up with Pete and reflects on all the drama – but she also has a confession to make - which Essex boy, or boys, has Chloe been locking lips with?!
