Kat Slater and Phil Mitchell were SUPPOSED to be getting married on Christmas Day, after their first attempt to get wed last year was derailed by her ex Alfie Moon.
After Kat found out that Alfie had been having tests for prostate cancer and Phil knew about it, she was furious with the pair of them for keeping her in the dark.
When Alfie went to get his test results, she dropped everything to be there for him, as he's the father of her kids, after all.
But when Alfie let the boys down yet again, she resolved to move on once and for all and she told Phil that they were getting married - next week!
Happy with her decision, Kat got ready for her nuptials in a gorgeous outfit and she headed off with the bridal party to the register office.
Unbeknownst to Kat, Phil was taking in some shocking news back in the Square, after Alfie admitted to him that he lied and he does, in fact, have prostate cancer.
