After he sent her a Twitter message on her 36th birthday saying he will 'repair' her 'heart' after he broke it by having an affair with the former model's best friend Jane Pountney, Katie responded – publicly, of course.
In a series of three coded (though blindingly obvious) messages on Twitter, the six months pregnant mother-of-four wrote: "My thought - Defeat your enemies with success."
She then added: "This has been the case - The saddest thing about betrayal is that it never comes from your enemies."
And then posted a third message, which said: "Trust takes years to build, seconds to break and forever to repair."
On Thursday, Kieran – dad to Katie's nine-month-old baby Jett - broke his silence for the first time on since Katie revealed he had cheated on her.
He wrote: "Happy birthday to my beautiful wife @MissKatiePrice I love you with all my heart forever and always."
He added: "I will repair your heart and I am looking for the light at the end of the tunnel for our fairy tale ending! Believe in me xx"
These messages followed Katie's cryptic Twitter poem on Tuesday that suggested the worst was over.
She wrote then: "HATE has 4 letters, but so does LOVE. ENEMIES has 7 letters, but so does FRIENDS.
"LYING has 5 letters, but so does TRUTH. HURT has 4 letters, but so does HEAL. "Transform every negative energy into an aura of positivity. It's our perception that makes the difference in the way we feel."
The mother-of-four - who has nine-month-old son Jett with Kieran, as well as son Harvey, 12, with Dwight Yorke and two children, Junior, eight, and six-year-old Princess with Peter Andre – is expecting a baby girl with Kieran and has said she still wants him to be at the birth of his daughter.
Will he? Won't he? Will they get back together? Watch this space...
