THE CAST of EastEnders look completely transformed with incredible fancy dress looks for Zack and Whitney's 'sten-do'.
Residents of Albert Square flocked to the scene The Queen Vic as they celebrated the seemingly happy couple's upcoming wedding.
But all is not as it seems when the festivities are interrupted by a shocking event EastEnders.
The party quickly descends into chaos as the underlying tension overwhelmed the crowd.
Bianca continued to look sour throughout the meeting as she confronted her apparent soon-to-be son-in-law Zack (James Farar).
Initially, the duo have a tense conversation at the bar before she sits him down after her shocking discovery.
He accidentally told her he slept with Lauren Branning (Jacqueline Jossa), causing Bianca to punch both him and Lauren in the face in the middle of Walford.
It seems that Zak is meant to look like a gangster, as he is dressed in a stylish old-fashioned suit and suspenders.
However, it doesn't seem like she's getting into the party spirit as she's dressed in a basic leopard print tracksuit.
But that doesn't mean the other cast members didn't enjoy the evening in their get-ups.
Billy (Perry Fenwick) and honey (Emma Barton) came to the pub dressed as the Flintstones in caveman attire.
They watched as Sonia (Natalie Cassidy) took a tense call as she opted for an ocean theme with fish-shaped headpieces and a scale-print top.
Jack Branning (Scott Maslen) kept himself very on-brand when he showed up in a mock appearance Police costume, making a joke about his career in law enforcement.
Meanwhile Callum Highway (Tony Klei) came as a prisoner in a black and white stripped suit and with a black eye patch.
Johnny Carter (Charlie Suff) was at the bar dressed in a 70s disco look while apparently handling a complaint with Ian (Adam Woodyatt) and Cindy Beale (Michelle Collins).
This will be part of Whitney's exit storyline next Shona McGarty announced she was leaving the soap after 16 years.
Last summer she informed the producers of her intention to quit the serial drama, calling it a “difficult decision”.
Shona explained: “It's all I've ever known. I pretty much grew up on the Square, so it feels like I'm leaving my home.
“But I had to put on my big girl pants and be very brave because life is so short and you feel that more and more as you get older.”
