Zack Hudson takes drastic action with Britney Wainright after cheating discovery in EastEnders

ZACK Hudson will be forced to convince troubled child Britney to lie to Whitney Dean on EastEnders.

Whitney and Zack are approaching the happiest day of their lives but Zack's huge cheating secret is looming.

With Whitney having given birth just days ago, it seems a given that the pair have chosen to cancel their wedding.

Whitney gave birth to daughter Dolly having gone into labour in the back of a taco van on her joint sten do with Zack.

Her waters broke just as Lauren Branning was gearing up to tell her best pal about her sordid sex session with her husband-to-be.

Although Dolly's arrival put a stop to Whitney ever finding out about the cheating scandal, young Britney is now in the know and Zack is panicked when she arrives back at their home in the aftermath of the birth.

In upcoming scenes, EastEnders fans will see Bianca bring Britney back home to Zack and Whit.

Immediately, Zack will be left finding a way to get Britney on her own.

He begs and begs her to keep quiet and not spill the beans on his illicit affair with Lauren, especially given Dolly's arrival.

However, they quickly become sidelined when they realise they need to tell their neighbours and pals that the wedding has been cancelled.

Britney is left internally conflicted and it begins to convey in her mood and behaviour.

This troubles Whitney who thinks that Britney isn't herself as a result of Dolly being born.

Aiming to cover his tracks as well as prove to Whitney not to worry, he says that she is just sad that the wedding is off.

As such, Whitney changes her mind and says that the wedding will still go ahead despite having an extremely newborn baby.

As Whitney and Zack begin to scrub up to head down the aisle both he and Lauren are consumed by their own guilt.

Later, Lily tells Britney about Whitney's difficult life and upbringing including his many failed romances and wedding woes.

It gives Britney food for thought as she wonders if she can keep quiet as Zack said or if she needs to tell the truth.

As Whitney goes down the aisle with baby Dolly in tow, Britney decides to make a stand as she gets up at the alter with Whitney and Zack.

She cracks and tells her all about Zack and Lauren's betryal.

How will Whitney cope knowing her husband and best friend did the deed behind her back?
