Dee Devlin has shared a bunch of photos from what she called 'the best weekend celebrating our two boy's birthdays!'
The 34-year-old also wrote: "Happy 5th birthday Conor Jr and happy 1st birthday baby Rían! We love you beyond words."
They marked the double-celebration as a family in the gorgeous surroundings of Saint-Tropez, having flown out there last week.
Among the jubilant scenes were Conor Jr whizzing down a bouncy castle slide while eldest child Croia enjoyed getting her face painted.
While over there, Conor Sr has been showing off the plush sights and sounds of their luxurious backdrop.
In one Instagram video, followers could see palm trees lining the streets of a posh-looking area as he cruised around in a Ferarri F8 Tributo which comes with an asking price of €262,000.
The Notorious did have his eye firmly on Phoenix, Arizona on Saturday night/Sunday morning, however, as he repeatedly reacted to a dramatic night of action at UFC 274 over the course of a few hours on Twitter.
He delighted in seeing two lightweight rivals whom he has exchanged verbals with in Tony Ferguson and Justin Gaethje both suffer devastating defeats.
Meanwhile he also congratulated the two men who had vanquished them in Michael Chandler and Charles Oliviera respectively.
Unsurprisingly, Chandler and Oliviera were both enthusiastic about the prospect of being the one to welcome McGregor back to the octagon whenever he makes his return from injury.
Despite it now being close to six years since he registered a win in the lightweight division, he remains the biggest money fight around so they and a few others will continue to clamour for that lucrative bout.
While his next opponent remains unclear, it's pretty evident at this point that a bulked-up McGregor favours making a return at 170lbs rather than draining himself to make the 155lb limit again.
In response to Oliviera, who was stripped of his lightweight crown for weighing in half a pound over the limit, McGregor tweeted: ”I’m not sure I wish to cut the weight. I am really enjoying being built like a refrigerator.
"I feel I want to fight at this size just to watch it back lol. But I’d love to fight the Brazilian, 100%! I love Brazil and I’m unbeaten against Brazil. All KO’s. I’ve some thinking to do.”
