Their characters Tanya Cross, Max Branning, Kat Moon and Alfie Moon will all be busy over the festive period as two long-running storylines come to a head.
Digital Spy can confirm that Max organises a secret wedding for Tanya after their wayward daughter Lauren trashes the plans for their original Christmas Eve ceremony.
While Tanya thinks the nuptials have been called off for now, Max won't give up and reveals on December 25 that he has arranged for them to tie the knot that day - even presenting his bride with a new wedding dress.
With Max's secret about to be revealed, however, will the Christmas Day ceremony actually go ahead?
Meanwhile, the Moons will also feature heavily at Christmas as the revelation of which Branning brother is Kat's secret lover will have huge repercussions for the pair.
