Well it 'tis the season to wear a onesie...

Dee Devlin and Conor McGregor are having a festive Christmas with son Conor Jnr - as they all wear matching onesies. UFC star Conor uploaded the adorable shot last night - with the six-month-old clearly loving the festivities of his first Christmas. And it's clear that the couple have gone all out to make the holidays momentous for Conor Jnr, with no expense spared doing up the Christmas tree. https://www.instagram.com/p/BdGvay3AZBG/?taken-by=thenotoriousmma Conor wrote: "Juniors first Christmas Eve ❤️ Happy Christmas everyone!" This is the first Christmas since Conor Jnr was born in May and they will be spending it with family. Dee and Conor will chow down on turkey with his sisters Erin and Aoife and parents Tony and Margaret today. https://www.instagram.com/p/Bc_dvnsg4gW/?taken-by=thenotoriousmma It comes as Conor has backed sister Erin to cha-cha-cha her way to winning Dancing With The Stars, which kicks off in the New Year. He posted a picture of them out looking at jewelery and said: "Do your thing sis I am proud of you." https://www.instagram.com/p/Bc_ZMZoABFJ/?taken-by=thenotoriousmma It's expected that Conor will attend one of the live shows but is understood to be planning to come on a non-elimination week to avoid taking over.
