On Thursday, pro golfer Dustin Johnson announced he will be taking a leave of absence from the sport to “seek professional help for personal challenges.”

Fox Sports reporter Robert Lusetich also casually dropped this bombshell infidelity allegation in a tweet:

Not a huge secret either that #DustinJohnson had affairs with 2 wives of PGA Tour players. One broke up the marriage. — Robert Lusetich (@RobertLusetich) August 1, 2014

A representative for Johnson was not immediately available for comment.

Johnson is engaged to Paulina Gretzky, the daughter of hockey legend Wayne Gretzky; Johnson popped the question in August of last year.

An unidentified source told Golf.com Johnson has failed three drug tests: once for marijuana in 2009, and twice for cocaine (once in 2012 and once in 2014).
