Dustin Johnson's having a busy week -- his fiancee, Paulina Gretzky, gave birth on Monday ... and then he flew out to Wisconsin for the U.S. open on Tuesday -- and it's all part of the family plan.
With Paulina ready to pop, the couple planned for a C-section delivery at an L.A. hospital on Monday -- giving Johnson enough time to attend the birth and still make it to the golf tourney, which starts Thursday.
Everything went according to plan, according to ESPN's Ian O'Connor, who says Paulina delivered a bouncing baby boy on Monday.
