Coleen Rooney "pointed the finger" at Rebekah Vardy as "the villain" who leaked stories to the press about her private life, the High Court has heard.
The wife of ex-England footballer Wayne Rooney was dubbed "Wagatha Christie" for her "sting operation" involving posting false stories on Instagram which later appeared in The Sun.
Mrs Rooney then said the source of those leaks was the account of Mrs Vardy.
Mrs Vardy, 38, was accused by Mrs Rooney of leaking stories over the course of five months. She denies the accusation.
At the High Court, Mrs Vardy's barrister Hugh Tomlinson QC said Mrs Rooney's posts were an "untrue and unjustified defamatory attack.
