Professional Mixed Martial Arts fighter Conor McGregor has grown his family! The UFC champion has announced the birth of his fourth baby with his partner Dee Devlin, whom he has been seeing since 2008 before his career took off. “Dee you are my hero.”

Conor shared a post yesterday revealing that he and Dee would be off to welcome their newborn this morning. “Up early tomorrow to bring our new baby boy in to this world, say a prayer for us! Let’s go Mammy.” Today, he shared a selection of images of the couple at the hospital with their little one. They welcomed a baby boy but did not yet reveal the moniker they’ve chosen for him. “Another chunky healthy boy into the world.”

The couple’s newborn joins the family with three siblings: brothers Conor Jr, 6, and Rian, 2, and a sister Croia, 4. Days before the arrival of baby #4, Conor shared an image out with his family for dinner. He reflected in the caption, “Family time. Proper Twelve Whiskey. Forged Irish Stout. Chicken curry and chips. Bacon fries. What more could the working man need. Nothing. Thank you God.” The MMA fighter announced his family was growing this past June during an interview on Live with Kelly and Mark. “We’ve also got another on the way. So there’s a lot going on,” he shared at the time.

Congratulations to Conor and Dee on the arrival of their fourth baby! We look forward to learning the name they choose for their little one, should they decide to share.
