Last week, MMA fighter Conor McGregor announced the birth of his fourth baby with his partner Dee Devlin. At the time, he didn’t share his newborn’s moniker. Today, he revealed the name the couple chose for their baby, a son.

Conor and Dee welcomed a baby boy on November 30th and they chose to name him Mack McGregor. Mack is the couple’s third son together. The couple share sons Conor Jr, 6, and Rian, 2, and they also have a daughter named Croia, 4.

Conor announced in an interview in June that he and Dee were expecting their fourth baby. “We’ve also got another on the way. So there’s a lot going on.” The MMA fighter also teased when Dee was giving birth with a post the day before Mack was born. With an image of the couple, who have been together since 2008, standing beside a car, Conor wrote on Instagram, “Up early tomorrow to bring our new baby boy in to this world, say a prayer for us! Let’s go Mammy.”

Congratulations again to Conor and Dee on the birth of their fourth baby! We wish them all the best as they welcome Mack into their family.
