Rebekah Vardy accepts that it is "possible" that her former agent Caroline Watt was "the source" of the leaks, according to her representatives.
The High Court libel battle is expected to draw to a close today, as lawyers for each of the women set out their cases. Coleen and Wayne Rooney were not present as they missed the final day of the trial to jet off on holiday with their four sons.
Hugh Tomlinson QC, who is representing Mrs Vardy, said that the case was a "very simple one" when "one clears away the conspiracy theories." He later added: "The suggestion that she is trying to hide something is quite wrong."

Speaking to the courts, Mr Tomlinson said: "Has Mrs Rooney proved that Mrs Vardy leaked the information from her post that she's accused of leaking?" He added: "Mrs Vardy's case is and always has been that she did not leak the information nor did she authorise anyone else to leak.
"She does not know to this day what happened. She does not know where this information came from."
He said that Mrs Vardy accepts that it is "possible" that her former agent Caroline Watt was "the source" of the leaks. He said: "She doesn't want to be in the position of accusing her friend and former long-term agent of doing something wrong.
"She sees, as everybody does, the indications that point that way. Her fundamental position is she doesn't know what happened."
The barrister continued: "Throughout this case, she (Mrs Vardy) has sought to find out the position. The very first thing she said to Mrs Rooney was 'send me the evidence, send me the posts'."
Mr Tomlinson described the arguments that Mrs Vardy had a "conspiracy to delete" messages or had deleted some in a selective way as an "incredible theory". He told the court: "There was an export of a very large number of Whatsapp messages.
"Why would Mrs Vardy, if she was destroying evidence, do it in that selective and complex way? If she was a wicked litigant who was trying to deceive the court by getting rid of damaging evidence, the idea she would do it by getting rid of images and not text .... simply beggars belief."
