Dee Devlin has thanked her 'heart and soul' Conor McGregor for going 'above and beyond' for her in an Instagram post.
The couple marked a double celebration over the weekend by throwing a party to celebrate their two sons' birthdays - Conor Jr (5) and Rian (1).
McGregor flew out their close friends and families to southern France on a private jet to attend the party.
Paying tribute to the former two-weight champion on Instagram, Dee wrote: "My heart and soul I love you forever you go above and beyond for me."
The post included numerous photos of the couple kissing and hugging, with McGregor commenting on it: "You are worth it all baby."
Sharing a number of family snaps on his own Instagram account, the Notorious said: "I feel like the richest man alive and it has nothing do with money."
The UFC star, Dee and their three children have been holidaying in Saint-Tropez since last week after McGregor picked up his new €3.5million luxury Lamborghini yacht.
He posted on Instagram after getting the luxury boat: "Today is the day!! We officially take ownership of our brand new Lamborghini Sport Yacht! But first.. the most important meal of the day."
McGregor later posted an image of himself driving the yacht alongside a video, captioned: "Trying to find the words. The supercar of the sea!"
The luxury yacht is known as "the supercar of the sea" and is 63 feet long while capable of producing 2000hp.
With a green hull, the luxury sea-liner pays homage to his whiskey brand Proper Twelve, which he sold in April last year for around $150m. Its luxury interior also catches the eye, and he has secured the Number 12 edition of the yacht in another tribute to his business.
His latest purchase joins a whole host of opulent toys, which also includes a series of cars such as the Lamborghini Aventador Roadster and his Urus.
McGregor's parents Tony and Margaret are also in France, with his father getting behind the wheel on the yacht last week.
Meanwhile, McGregor is on target to achieve his goal of becoming a billionaire before he is 35, an expert has predicted.
Leading US sports analyst Andrew Petcash claims the fighter will beat his own ambition by at least a year based on current earnings.
McGregor, 33, told ESPN in 2020 he would be a billionaire by the time he was 35.
But now it looks like the Notorious is set to achieve it by the time he turns 34 in July.
Sports entrepreneur Petcash, who compiles online sports newsletter the Petcash Post, posted his McGregor forecast on Twitter.
He tweeted: “Conor McGregor will be a [dollar] billionaire this year, (earning) $235m from fighting and a $600m deal off the ring.
“McGregor makes a lot from fighting. A study by OLBG found that he makes over $8m for every minute in the octagon.”
