He's one of the loudest, most braggadocios fighters in UFC. Despite what they say about fatherhood changing one's perspective in life, that's probably not going to change for The Notorious.

UFC fighter and current Lightweight Champion Connor McGreggor and his wife, Dee, welcomed Connor McGregor Jr. into the world on Friday night. On Sunday, the couple posted the first pictures of their little champ.

Dee and Junior are doing great everyone! Thank you for all the kind words, I am one proud and blessed Daddy ❤️

By the afternoon, McGregor was already showing off Junior's left hook.

We can land the left paw from anywhere. Who wants it.

Junior already has his own Instagram account. It's verified, too, which must break some sort of record for youngest person ever to have a verified account. He already has 48,100 followers even though he has yet to post a selfie.
