It sounds like hockey great Wayne Gretzky had some stern words with his future son-in-law, Dustin Johnson, long before revelations of his hard-partying ways hit the press.

Sources tell FOX411 that Gretzky previously talked to Johnson, who is engaged to his 25-year-old model daughter, Paulina, cautioning him to clean up his act, or the wedding was off. We’re told that the family was aware of his penchant for partying, and that Wayne sought to be a positive influence, and offer help.
