The 34-year-old MMA fighter and his fiancee Dee Devlin have welcomed another boy - a sibling for Conor Jr., six, Croia, four, and two-year-old Rian - into the world and couldn't be happier.
Conor wrote on X, formerly Twitter, on Thursday (30.11.23): "My baby boy is born! Mammy and baby doing amazing, 8.1lbs of prime Irish double champion beef!(sic)"
And he also shared a series of photos of the "chunky" little boy on Instagram.
He captioned the post: "Another chunky healthy boy into the world. Dee you are my hero [heart and prayer emojis] (sic)"
On 29 November, the former UFC featherweight and lightweight champion had revealed they were preparing for the baby's birth.
He had shared a photo of himself and Dee and wrote on X: "Up early tomorrow to bring our new baby boy in to this world, say a prayer for us! Let’s go Mammy".
Conor confirmed in June he was set to be a dad again.
Speaking on 'Live with Kelly and Mark', he said: "I have three children; I've got two boys and a girl.
"My oldest one, Conor Jr., is six, my daughter Croia Mairead, four, and my youngest son Rian has just turned two. So, things are going well.
"We've also got another on the way, so there's a lot going on."
Conor - who met Dee in 2007 and got engaged in August 2020 - also told how his eldest son is learning more about fighting "techniques", and his daughter is starting "big school" soon.
He added: "Training is picking up with Jr. He's starting to get his techniques correct.
"We are very excited back home.
"A lot great is happening right now. Very blessed and very thankful."
