Conor Jr, Croia and Rian woke up to an array of presents that would have made Hamleys blush – with McGregor thoroughly enjoying playing the role of Santa Claus.
Indeed, Santa’s elves must have been working hard this year because among the presents were a Nintendo Switch, Hungry Hungry Hippos, and a host of games, including Minecraft.
Other gifts included a slush puppy machine, a girl’s bike and a children’s kitchen set, but the cream of the crop has to be two miniature toy Lamborghinis.
The cars, one blue and one red, are in-keeping with McGregor’s own love of motors; the Notorious has a £2.5million car collection which includes a real Lamborghini and a stunning Ferrari.
But Christmas is all about the children, and sharing the photos of their gifts online, McGregor wrote: “Santy is in Ireland!!”
The Irishman and partner Dee Devlin welcomed their third child into the world earlier this year when little Rian was born in Dubai.

His children must surely have been delighted with their haul, and sharing a photo of Rian on Instagram on Christmas Eve, McGregor beamed: “Rian’s 1st Christmas, we are buzzing! Happy Christmas everyone.”
Responding to the photo, Dee said: “So excited!!”
Once Christmas is over, McGregor’s attention will turn to making his UFC comeback.
The 33-year-old has been out of action since suffering a horror ankle break in his trilogy fight with nemesis Dustin Poirier last summer.
And his comeback fight could be against lightweight champion Charles Oliveira, who revealed that he wants to fight the Dubliner next year.
The Brazilian told Sherdog: “May would be a wonderful date. Conor challenged me asking a date, and tweeted Ireland vs. Brazil 2.
“Not only him, but also myself and all the world wants to see that fight. So let’s make it happen. I’m waiting for him in May.
“It may be in welterweight, lightweight or middleweight, with my title on the line or not. Just choose and I’ll be ready.”
