Earlier today, Katie stunned fans after a message was posted on her Twitter account, saying that she will be divorcing Kieran following an alleged affair with a friend.
Ex glamour model Katie - who has just confirmed that she is six months pregnant with their second child - has now taken to the social media site again, this time to blast part-time stripper Kieran and the alleged other woman.
She tweeted: "She is a wh*re, home wrecker sl*t.
"Kieran is a disgusting human being doing this after I've just had a baby and still doing it till I caught them.
"No human being deserves this especially being 6 months pregnant."
Katie then added: "Worse pain in the world."
Katie's rep told Reveal that they were unable to comment. Kieran has not yet commented on the claims.
The couple married in January 2012 on a beach in the Bahamas and welcomed their first child, Jett, the following summer.
In October 2013, Katie had told Reveal: "[Kieran] is brilliant, that's why I'm saying to everyone that I don't have to worry about being with someone else again. He is here to stay. Third time lucky."
