Favre filed the lawsuits earlier this week in Mississippi -- naming state auditor Shad White as a defendant in one of the suits as well.

The Green Bay Packers legend claims in the suits all three defamed him when talking about his alleged role in a welfare funds scandal in Mississippi.

Favre said McAfee made some of the remarks on his podcast, alleging the former NFL punter said the ex-QB was "stealing from poor people in Mississippi."

The Hall of Famer claimed Sharpe muttered defamatory comments on his FS1 show -- when he said Sharpe called Favre a "sorry mofo to steal from the lowest of the low."

As for White, Favre says the Mississippi official has "shamelessly and falsely" attacked him for months "in a brazen attempt to leverage the media attention generated by Favre's celebrity to further his own political career."

FYI, White and his office were the ones who initially discovered the alleged misuse of welfare funds, claiming over $70 million intended to go toward the needy in Miss. actually went elsewhere -- including to Favre as well as projects closely associated with the Hall of Famer.

Favre, though, has denied any wrongdoing in the case ... insisting back in September, "I have done nothing wrong."

Favre is suing the trio for unspecified damages.

A spokesman for the State Auditor's office said Thursday in response to the suits that "everything Auditor White has said about this case is true and is backed by years of audit work by the professionals at the Office of the State Auditor."
