The social media user wrote: '@KerryKatona7 and @MissKatiePrice just keep getting married and having babies. F***ing idiots the pair of them.'
And despite Katie's social media silence since Wednesday (when she revealed her husband Kieran Hayler had been cheating on her), Kerry responded to the troll, writing: 'sometimes life doesn't always work out how you planned! But then again not everyone is perfect!!!!'
Both women have children by three different fathers, with Kerry having just given birth to her fifth, and Katie's fifth on its way.
Fans of the pair were quick to lend their support, with one writing: 'personally I think the (sic) both beautiful people And deserve the best in life #tooquicktojudge'
Another added 'lifes too short; one life live it! Be happy x'
Good pal Michelle Heaton also spoke out about the divorce drama, telling OK online that she is going to 'prove to the world how good a friend I am to her by remaining silent and letting Katie tell everyone in her own time.'
'She knows where I am if she needs me and she knows she can count on me,' the Liberty X singer added.
Katie has been left devastated after discovering that her husband of just over a year, Kieran Hayler, has been cheating on her with her best friend Jane Pountney.
According to The Sun, Katie became suspicious after catching the pair having a 'drunken kiss' whilst on holiday in Cape Verde.
After returning to the UK, Katie checked Kieran's phone, discovering a Whatsapp message from Jane reading: 'Has she left yet. Can't wait to see you.'
Last week Katie confirmed the 'full blown sexual affair' on Twitter, but has been silent on the matter since a statement she released on Wednesday evening, telling the world she intends to divorce her love-rat husband.
