The residents of Walford are donning their best fancy dress in upcoming scenes to celebrate Zack Hudson and Whitney Dean's joint 'sten-do'.
However chaos will soon descend on the couple's party after Bianca Jackson (Patsy Palmer) discovered the groom-to-be (James Farrar) was cheating on her adoptive daughter (Shona McGarty) with best friend Lauren Branning (Jacqueline Jossa).
In the first look snaps while the majority of the square enjoy the bash, Bianca and Zack can be seen sat together with the mother-of-four torn about wether to reveal the truth to Whitney.
Billy (Perry Fenwick) and Honey (Emma Barton) are dressed as Fred and Wilma Flinstone while Eve Unwin (Heather Peace) looks unrecognisable as she arrives as her partner Suki Panesar.
Actress Patsy announced her return to the soap last month, writing: 'I'm so excited to be reprising the role of Bianca. EastEnders holds such a special place in my heart, so it's always a pleasure to be back.'

Last week's episode saw Lauren and Zach share a steamy kiss in the alley way after stepping out together to let off some steam.
Patsy's character first hit screens in 1993 before Patsy quit in 1999 to spend more time with her family.
She returned to screens in 2002 for a special and made further returns in 2009 and 2019, before her upcoming comeback.
It comes after Shona, 31, revealed last year that she would be quitting the soap after portraying Whitney for 15 years, after joining at the age of 16 in 2008.
Speaking to The Sun on Sunday about her decision to leave Albert Square, Shona said: 'I have decided to spread my wings and will be leaving EastEnders. I have loved my years in the show.'
A source told the publication that it 'wasn't an easy decision' but that Shona feels now is the right time to 'try something new.'
They added: 'She is hoping the door will be left open for her character to return one day, but nothing is guaranteed and it is all in the hands of the scriptwriters.'
As the adopted daughter of the infamous Bianca, Whitney was part of several hard-hitting storylines.

It comes after former EastEnders star Don Gilet was announced as the new lead in crime drama Death In Paradise as he steps up to the role as Detective Inspector Mervin Wilson.
The actor, 57, will make his debut in a feature-length Christmas special later this year, before a brand-new series in 2025 as his character arrives on the idyllic island of Saint Marie from London, and isn't overly pleased with his new surroundings.
But prior to his role in the sunny Caribbean, the star is best known for appearing in as Lucas Johnson in the BBC as well as an appearance in Doctor Who.
Don made his first ever television debut on the Channel 4 dating show Streetmate, where he was interviewed as the friend of a participant.
However he got his breakout role in 2001 as Johnny Lindo in Babyfather, where he starred opposite his future EastEnders co-star Diane Parish.
