Former glamour model Katie stunned fans earlier today by accusing Kieran of having an affair with a friend, adding that she is pulling the plug on their marriage.
Mum-of-four Katie - who is expecting her second child with Kieran - also branded her husband "a disgusting human being" while continuing to blast him on Twitter.
Part-time stripper Kieran, meanwhile, has remained silent. Katie's rep told Reveal that they were unable to comment.
Since announcing her shock news, Katie's fans have been inundating her with messages of support, as have her celebrity friends too.
Rylan Clark, who first found fame on Katie's reality show Signed By Katie Price, sent a simple heart icon to his heartbroken pal, along with a couple of kisses.
Former TOWIE star Frankie Essex, meanwhile, tweeted: "Omg I can't believe what I've just heard, sending lots of love to @MissKatiePrice they don't deserved to have you in their lives #sick.
Aisleyne Horgan Wallace, from Big Brother, said: "Poor darling.... Be strong, hearts mend in time. He's not worthy of ur pain."
Responding to one of Katie's tweets, in which she branded the woman who Kieran allegedly cheated with a "wh*re", Aisleyne added: "SCUMMY TRAMP B****."
Meanwhile, Katie's fans have also been bombarding her with messages of support, with one saying: "I'm so sorry for your hurt x."
Another of her followers said: "Surround yourself with your family now Katie at this hard time."
Katie and Kieran married in January 2012 on a beach in the Bahamas and welcomed their first child, Jett, the following summer.
On Sunday, it was revealed that Katie is six months pregnant with Kieran's second child.
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."
