After initially vowing to divorce her unfaithful husband, the former glamour model had a change of heart, vowing to stick by him as he sought treatment for what's been described as an addition to illicit thrills.
Tweeting last night, she told fans: "So happy I was strong enough to stick by Kieran. Therapy has been fantastic. #newman but I knew I was always the one.
"He knows I'm the #fullpackage I feel sorry for the try hards who didn't get him and he didn't want them easy S***s."
Kieran and Katie married in the Bahamas in January 2013 following a whirlwind engagement. Things appeared to be rock solid between them as they welcomed son Jett that summer and announced a second pregnancy the following year.
But just as news of the pregnancy was confirmed, it emerged that Kieran had cheated on Katie with two of her best friends.
Katie was understandably heartbroken and told fans that Kieran would "no longer be part" of her life. However, she later did a U-Turn and promised to stick by him.
Their second child, Bunny, was born in August.
The family are now preparing for their first Christmas since the cheating scandal broke – and their first Christmas with daughter Bunny.
Some fans, however, have questioned Katie's decision to forgive Kieran and move on, and others are concerned she may get hurt again.
Last night, Katie tweeted: "Everyone deserves a chance and he is doing everything to prove himself only time will tell but at least we are trying.
"People are capable of changing if they want to and if he chooses to mess up it's his choice, no other chances ever."
