In short, Rooney suspected Vardy was behind the leaks, so she blocked everyone but Vardy from seeing the posts on her private account.
When asked about the recent scandal involving Rebekah Vardy and Coleen Rooney - the latter has accused the other of leaking fake stories about her to The Sun - Stacey admitted she isn't aware that anyone around her has done the same thing, but that she tries "really hard to focus on the good things in my life" rather than worry about fake stories.
An insider exclusively told MailOnline: 'Rebekah has been incredibly stressed and hasn't stopped sobbing all day, which is very out of character for her.
They added: "Maybe to Coleen's camp, they were overshadowing them and becoming a bigger brand and that's why this has been so public".
In a previous tweet, Vardy refuted claims made by reality TV star Danielle Lloyd - the wife of footballer Jamie O'Hara - who waded into the row with an appearance on ITV's This Morning.
Coleen Rooney is probably not in need of any new sources of income after being married to English soccer star Wayne Rooney for more than a decade, but she may have a career as a detective waiting for her if she ever has any interest.
Coleen has since denied the suggestion she is threatened by Rebekah and Jamie's brand as a couple.
"Now she's getting relentlessly trolled and is just beside herself".
A friend of Coleen's reportedly hit back: "Coleen has never been interested in being a brand, that's nonsense".
Opening up on The Jeremy Vine Show, Nicola said: "I don't know Coleen but I do know Rebekah and what she's going through is what nobody should have to go through so publicly".
"There has been so much information given to them about me, my friends and my family - all without my permission or knowledge". (Those on my private account must have been wondering why I haven't had stories on there for a while.) Over the past five months I have posted a series of false stories to see if they made their way into the Sun newspaper.
"I'm trying not to be too serious here but I've seen the impact it's actually had".
Opening up about when she discovered which account was the culprit, Coleen added: "It's been tough keeping it to myself and not making any comment at all, especially when the stories have been leaked, however I had to". And you know what, they did! This led to apparently fake articles about Rooney seeking baby gender selection treatment in Mexico, a planned return to television, and a flood at her new-build mansion appearing in the Sun.
'Now I know for certain which account/individual it's come from.
They did, and the only person who had viewed those Instagram stories was Vardy.
In response, Vardy has suggested that someone else with access to her Instagram account may have been responsible for passing on information.
