Conor McGregor has been hanging out with the Prince and Princess of Monaco on his holidays.
The UFC star rubbed shoulders with the royal couple as he and partner Dee Devlin soaked up the sun on the island of Corsica.
McGregor, 32, hit the Mediterranean Sea with Princess Charlene, 42, on a pair of futuristic-looking water bikes.
He and his long-term partner Dee were also pictured chatting and posing with Charlene's husband Prince Albert II.
The Crumlin man said on his Instagram that he and Princess Charlene, a former Olympic swimmer, were partnering up to raise money for water safety awareness.
He wrote: "A Great day racing the water bikes with Princess Charlene of Monaco.
"A phenomenal athlete and Olympian, we are teaming up for a 180km voyage in September to raise awareness in water safety. I cannot wait!
"We will be utilising my training under the McGregor F.A.S.T program to excel on these mounted water bike devices, which are incredibly good!
"It is like Freedom out there! Thank you for the great day for my family Your Highness. In aid of the Princess Charlene of Monaco foundation."
Prince Albert II is one of the richest royals in the world with an estimated fortune exceeding €1 billion.
The 62-year-old began his reign in 2005 following the death of his father Prince Rainier III.
Like Conor and Dee, the Prince and Princess have two children together five-year-old twins Princess Gabriella, Countess of Carladès, and Jacques, Hereditary Prince of Monaco.
The pair recently celebrated nine years of marriage together on the French-ruled island.
Mixed martial artist McGregor has been spotted hanging out there in the picturesque town of Calvi.
He was even pictured with rugby giant Eben Etzebeth with the 6′ 8″ World Cup winner dwarfing the former lightweight champion.
McGregor had been in the south of France where he celebrated his 32nd birthday and unwound on the beach after announcing his retirement from the UFC earlier this year.
The Dubliner has, among other things, been jet-skiing, drove around in a Lamborghini and shown off to his 36 million followers a €542,000 watch that is his latest eye-watering purchase.
Now it seems he and Walkinstown native Dee have become chummy with one of the world's most famous couples.
