In an unpleasant Instagram bluster the 43-year-old star alluded to the NHS specialist as “nauseating” and made a progression of stunning allegations against her.
But a source has dismissed her claims about the 32-year-old as “not just cruel – but totally untrue”.
They also suggested Katie‘s jealousy fuelled the rant, which came on the eve of Emily appearing on Loose Women – Katie’s old show.
The medic is going to appear on the panel this afternoon to speak about her book Growing Up For Girls.
Pricey was on the ITV show’s panel for two years but hasn’t appeared since announcing her engagement to Kris Boyson in 2019.
The source said: “Seeing your ex’s new wife appearing on your old show might hurt, but this is just jealousy – and it shouldn’t be an excuse for such a vile attack.”
Emily cares for Princess, 14, and Junior, 16 – Katie’s children with singer Pete – when they stay with the couple and their own kids.
It is believed Katie flew into a rage after reading Emily’s remark that she “works hard to keep things consistent” for the children in a magazine.
“I think you’re a disgusting person so stop trying to interfere in my life.”
Katie also falsely claimed: “So cringe she has used my children to make money in photo shoots yet covers her own children’s faces up!”
And she insisted Emily had stopped her daughter from visiting her when she was in The Priory saying: “She is so jealous of my relationship I have with Princess and puts me down.”
“The claims she made are not just so cruel but totally untrue. Emily would never stand in the way of Princess seeing her mum.
“Looking after another person’s children is never easy and she has been very careful to be respectful of Katie and has never once so much as spoken about her publicly.
