Rebekah Vardy is suing Coleen Rooney for libel over their online fallout last year, according to a court listing.
Rooney, the wife of former Manchester United and England striker Wayne, claimed Vardy - who is married to Leicester City striker Jamie - had been leaking stories about her to the press.
Vardy, 38, denied any wrongdoing and later said the stress of their public row had caused her to have severe anxiety attacks.
In October 2019, Rooney accused Vardy on Twitter of leaking private Instagram stories about her to The Sun newspaper.
She claimed she had set the privacy settings to ensure the stories were only visible to one account, which belongs to Vardy's.
