Conor Jack McGregor Jr. was born May 6 at Coombe Maternity Hospital in Dublin, Ireland. He weighed 8 pounds and 14 ounces.
From the beginning, McGregor has touted the youngster's boxing ability. He talked about his son's ability to "land the left paw from anywhere" in the second picture he posted of the newborn on social media.
Now he's back at it again.
McGregor posted a photo Thursday morning of his son with all of his title belts. He wrote: "Let's go get some boxing ones now son."

He posted another photo of "Junior" last weekend, again referencing his infant boxing prowess.
"The undisputed 9-pound champion of the world stays ready always! Even when drinking his milk," McGregor wrote on the post. On Wednesday he posted a photo of his son sleeping, writing: "Dream big dreams my son."
McGregor Jr. has an Instagram account and already has more followers than most people. His following currently sits at more than 66,000. The verified account is operated by his dad and mother, Dee Devlin.
McGregor and Devlin have been together for more than eight years.
