In July, Rebekah Vardy lost her High Court libel battle with Coleen Rooney in a case dubbed 'Wagatha Christie'.
Rooney, the wife of the former United and England striker, had accusing Vardy of leaking private stories about her and her family to The Sun.
Vardy denied the allegation but after a highly-publicised court battle, a judge found that Rooney's accusation was "substantially true".
Red Devils supporters used the verdict to mock Vardy in Thursday's Premier League match between Leicester and United, which ended in a narrow 1-0 win for Erik ten Hag's side the King Power Stadium.
In a clip circulating on social media, away fans can be heard singing the chant "Jamie Vardy, your wife is a grass".
They also repeatedly chanted "Rooney, Rooney" as a tribute to their former striker and record goalscorer.
It is not the first time that opposition fans have used the court case to mock Vardy on the football pitch.
Back in May, while the case was still ongoing, Chelsea fans used the same chants against Vardy during a 1-1 draw with Leicester.
Rebekah Vardy says she and her family have been subjected to abuse since Coleen Rooney first made her allegation in 2019.
"As I explained in my evidence I, my family and even my unborn baby, were subjected to disgusting messages and vile abuse following Coleen's post and these have continued even during the course of the trial," she said.
"Please can the people who have been abusing me and my family now stop.
"The case is over. I want to thank everyone who has supported me."
Vardy played 87 minutes of the match on Thursday as Leicester were beaten at home, with Jadon Sancho scoring the winning goal for United.
Victory for the Red Devils moves them up to fifth in the table, while Leicester remain bottom with just one point from their opening five matches of the season.
