BBC's EastEnders is gong to launch a huge new secret storyline in the New Year.
Just when viewers are given some breathing room after the explosive events of Christmas with Sharon and Keanu's affair being exposed, things will get even bigger.
The soap has teased a cryptic new plot that could be 'catastrophic' if it were to be exposed.
On Friday January 3, the new secret storyline will begin.
The official synopsis reads: "More than one family is torn apart following the past events of Christmas Day and despite Walford’s biggest secret being exposed; an even bigger has now formed.
"Only a handful of people know the truth and whether or not it will remain hidden, only time will tell.
"One thing is certain however, if it ever did come out, the consequences would be catastrophic."
But before viewers can get to this moment, they will get to watch Phil Mitchell's explosive revenge as he finally learns that Sharon is carrying Keanu Taylor's baby and not his.
As Christmas week begins in Walford, Sharon and Keanu are oblivious to the fact Phil is getting closer to working out their sordid secret... quizzing anyone who might be able to help him to unearth the truth about Sharon's baby.
As Louise and Keanu arrive home from the hospital with baby Peggy, the rest of the Mitchells are distracted by the new addition to their family.
But Phil's mind is still on working out the truth, and as the Mitchells and Beales celebrate at a welcome home party Kathy has thrown for the new parents, everyone is oblivious to the fact all hell is about to break loose because Phil's worked everything out.
As Christmas Day arrives, Sharon and Keanu have no idea that by the end of the day both their worlds will be shattered.
Phil puts the ultimate revenge plan into action and he's determined to make sure that everyone involved gets their comeuppance.
Everyone knows that Phil's not a man to be messed with, but as the Mitchell family is ripped apart, just how far will Phil go to teach Sharon and Keanu a lesson?
