"Many radio and newspaper journalists have attempted to put a sad smear on the hospitality given to the Hull City directors and guests at Ninian Park last Saturday," said Ridsdale
"Our guests were understandably relieved and overjoyed that the results from matches played last Saturday appear to have guaranteed their survival in the Championship.
"As a gesture to congratulate them, all of our visitors were offered champagne, red or white wine, beer or soft drinks.
"It is no surprise that many accepted the offer of a glass of champagne."
Mr Ridsdale continued: "Adam Pearson was standing at the entrance to our directors box some 30 minutes after the final whistle of our game and long after all supporters had left.
"I handed him a glass of champagne which he accepted. As I have not had an alcoholic drink for some five or six weeks I did not join him.
"This gesture had nothing to do with Leeds United's future. I have made my position clear on the current position of Leeds United.
"I am saddened by their current plight and have always wished them well as I continue to do so."
Ray Fell, chairman of the official Leeds United Supporters' Club, said he accepted Mr Ridsdale was simply having a drink with the Hull chairman.
He said: "The story has circulated in Leeds and I think some fans have got the wrong impression.
"I've known him for a long time and I don't think he would celebrate Leeds' fall.
"I can't imagine it was any more than two friends having a drink."
