Conor McGregor/Instagram Dee Devlin/Instagram Second Child on the Way for Conor McGregor Devlin, 31, confirmed her second pregnancy back in July when celebrating the UFC champion’s 30th birthday on Instagram. “Thank you for being you! Love you to bits from me, Conor jr and the bump,” she captioned an image of her boyfriend on a yacht. Following the release of McGregor’s whiskey Proper Twelve in September, Devlin shared a photo of the two and congratulated the then-dad-to-be in the caption with, “Our (growing) family so proud of you!” “Looking forward to drinking Proper Twelve with you in just a few months,” she teased. Before the couple’s firstborn arrived, McGregor told reporters he didn’t want his son to be involved in “celebrity s—.” “I’m gonna have this baby, take a little time and see what way I feel after that,” he said in 2016. However, McGregor and Devlin have been public about parenthood on social media, sharing occasional photos of Conor Jr. to their combined over 32 million Instagram followers. UFC Champion Conor McGregor Welcomes Son Conor Jack The couple met back in 2008, well before McGregor’s UFC success, according to the Irish Mirror. And the new father of two credits much of his success to the support of his beloved. “She has helped me throughout this career. If it wasn’t for her, I probably wouldn’t be where I am today,” he told MMAFighting. In December, McGregor shared an adorable video of his son hitting a punching bag while he trained. “We are never too young to start and never too old to learn,” the proud dad captioned the clip.
