As Conor McGregor was preparing for the third fight with Dustin Poirier, he was doing so while preparing to welcome a second baby boy and third child into the world. This has at least gone according to plan, as Dee Devlin has successfully given brith to their son Rian. Over the years, McGregor has discussed how important being a father is to his motivation and success, both in and outside the Octagon. He has attributed this to helping him clean up his act, in terms of his issues with the law and making less than ideal decisions in life. This was especially prevalent in his two most recent bouts, as he shared mutual respect with both Donald Cerrone and Dustin Poirier. While that only worked in his favor with one of those two bouts, he had nothing but nice things to say in the lead-up to those bouts, attributing it to fatherhood. https:\/\/www.instagram.com\/p\/CNkUhllJVEh\/ Conor McGregor Celebrates Birth Of Third Child In the buildup to his rematch with Dustin Poirier, Conor McGregor explained that he was awaiting the birth of a third child.
