Rooney has been at the centre of allegations about his private life and with a trip to former club Everton looming, there has been a huge amount of speculation as to whether the 24-year-old will be involved or not.
Toffees defender Phil Jagielka has already wound up the situation, claiming Rooney can expect a hostile reception at Goodison Park.
But Ferguson has no intention of adding fuel to the fire.
"Let's put it to bed straightaway," said the United boss. "I am not discussing any of my players' personal lives."
