Julia recently wrote a book about her experiences of being cheated on by her ex-husband, Richard.
The former Sky Sports presenter is thought to be dating Lucie Rose – his daughter’s friend – after having an affair with her.
His cheating resulted in the end of his 36-year marriage to Julia.
She has since written a book on how to cope with the ordeal, called The MANScript.
As she was promoting the self-help book, she had an awkward encounter with Eamonn during the fiery This Morning chat.
She explained how Richard contributed a statement for the book, where he wrote: “If you really love your wife but are tempted to get a bit of excitement elsewhere, you have to be prepared to lose the one you really love.”
The 60-year-old added how Richard “deeply regrets” what he did and would not do it again should the clock be turned back.
However, Eamonn appeared to have a problem with this and demanded to know how Richard could say these things despite allegedly being with his new partner.
He demanded: “Excuse me. Is that really true because Richard is still with Lucie so he wouldn’t be writing that?”
Julia fought back: “No, he did Eamonn, that’s 100 per cent true.”
And after the awkward exchange – which saw Eamonn question if there was a problem with their relationship on numerous occasions – viewers flocked to Twitter to discuss what they had seen.
Now, Julia has spoken exclusively to Express.co.uk to discuss what she made of the backlash.
She explained: “I think in fairness to Eamonn – like he said – Richard isn’t there to speak for himself so I think from his point of view he was trying to speak on Richard’s behalf.
“What he said was valid from the point of view that there was two people in the relationship.
“There are reasons why these things happen but what he was saying about my situation and about Richard’s was actually using a ‘classic justification’ script.”
Julia went on to explain how the ending of her marriage was focussed on helping her daughter recover from a “serious illness” and worried Richard felt “left out”.
She went on: “What Eamonn did was really almost say, ’Well you’ve got a very sick daughter, you’re coming and going in different countries and you live your life in the public eye almost as if that was a reason for having an affair,’ and that’s what we call a classic justification script.
“That is not justification because an affair is about a choice,” Julia insisted.
She continued: “Yes, there might have been something going on in your relationship but that doesn’t mean your partner is to blame – there’s always a choice.”
Express.co.uk contacted a representative of Eamonn Holmes and This Morning who both declined to comment.
This comes after Julia responded to her former sister-in-law’s tweets.
The MANScript by Julia Keys and Jacqui Coles is out May 1st £12.99 online and in all good bookshops published by Hashtag Press.
