Fans were left rather stunned earlier today when Katie's official Twitter account posted a tweet accusing Kieran of cheating on her while she is pregnant with their second child and saying they were to divorce.
A rep for Katie declined to comment while Kieran has not responded to the allegation.
But the lack of information available about the split and cheating accusation hasn't stopped Katie becoming a trending topic and thousands of Twitter users sharing their opinions on the former glamour girl and her relationship.
And it's all too much for X Factor star Rylan, who has hit out at people taking pleasure in his pregnant friend's heartbreak.
Rylan tweeted: "Katie is a normal girl inside and out and no one deserves what she's going through today. The jokes people are making are disgusting."
Earlier in the day, he'd also shown his support by tweeting a heart icon to his pal.
Katie and Kieran married in the Bahamas in January 2013 following a whirlwind romance and Christmas proposal. They welcomed their son Jett that summer and, just three days ago, confirmed they are expecting baby number two, making Katie's divorce news all the more shocking to some.
Katie hasn't held back on Twitter when it comes to her emotions, branding the alleged other woman a "wh*re', 'homewrecker and 'sl*t', adding: "No human being deserves this especially being six months pregnant."
She added: "Kieran is a disgusting human being doing this after I've just had a baby and still doing it till I caught him… Worse pain the world."
Kieran has not replied.
