The little one arrived a few days ago – as confirmed by proud granddad Tony McGregor.
And now gleaming dad himself Conor has shared the news in person, posting a snap of his gorgeous son shortly after the birth.
“Dee and Junior are doing great everyone!” the MMA star wrote. “Thank you for all the kind words, I am one proud and blessed Daddy.”
We love that little Conor McGregor Jnr is just a ball of absolute cuteness. He can be seen in the photo snuggled into his mama, his big blue eyes open and taking in his surroundings.
As an aside – Dee Devlin looks pretty incredible herself.
Baby Conor was delivered in the Coombe Hospital in Dublin and weighed in at 8lbs 14ozs.
Congrats to the entire McGregor-Devlin family!
