"I don't know about Brad Pitt, leaving that beautiful wife (Jennifer Aniston) to go hold orphans for Angelina," Douglas is quoted as saying in this month's GQ. "I mean, how long is that going to last?"
However, Douglas told "Extra" he never delivered the quotes and when he asked the GQ writer for proof, she claimed to have "turned the recorder off," People magazine reported Monday.
Douglas said he has apologized to his "good friend" Pitt and Jolie, "who does wonderful work for the United Nations."
GQ Executive Editor Andy Ward issued a statement to People Monday saying the magazine stands "100 percent" behind the reporter and the accuracy of the quotes.
"For him to suggest we made them up is laughable," Ward said. "Still, we like the guy and hope all this attention will help his movie."
Douglas has been making the media rounds promoting his new film, "The Sentinel."
