The Only Way Is Essex's 200th episode airs tonight and it all kicks off as Megan McKenna makes an appearance.
It's as all of Essex’s favourites gather to celebrate all that is great and good about Essex with a 1920s themed celebration thrown by the original Essex golden couple, Arg and Lydia.
There’s a surprise in store for all when Pete reveals Megan as his mystery date.
She joins best friends Courtney and Chloe M, Danni approaches the trio with support from Georgia. But as Megan steps in to defend Courtney, Chloe S overhears from afar and takes great offence to what she’s heard...
There's quite the showdown between the girls with heated words exchanged from both sides of the table, as Chloe S squares up against Megan, Courtney and Chloe M – is another Essex feud about to erupt?
The next morning, Danni and Courtney finally find themselves alone together – will they clear the air? And Chloe S reflects on the night before with Pete – and has a confession. Which Essex boy, or boys, has she been locking lips with?
Away from the Danni / Courtney drama, Mike and Chloe M’s blossoming friendship has hit a standstill after Chloe M hears he’s taken someone else on a date. But when Kate steps in to defend Mike, she and Chloe M have another awkward conversation at the dinner table.
Elsewhere, Kate and Dan hit a rocky patch after she accuses him of neglecting her.
Plus, as TOWIE celebrates 200 episodes, look out for references to some faces from the past, including Sam, Joey and even Mr Darcey the pig.
