Conor McGregor has announced he will compete for the Princess of Monaco's team in a Marathon Endurance Race across the Mediterranean next month.
The Notorious was pictured with Princess Charlene while on holiday in the French Riviera last month and will compete in the race, which gets underway on September 12.
Revealing the news on Instagram, McGregor said: "Joining Princess Charlene’s team for the Marathon Endurance Race is both an honor and a challenge. When I commit, I always train hard, and we plan to win!
"The Princess’ foundation works in over 30 countries promoting fitness and safety in water sports.
"I appreciate the support and encouragement I have received in Monaco. Let’s go team @mcgregorfast!"
The water biking contest will see two relay teams of four athletes compete against one another in an overnight race.
It begins in Corsica on September 12 and finishes at Monaco's Yacht Club the following day. It is expected to last 24 hours.
Princess Charlene is both the event's chief organiser and the defending team champion and trained with McGregor when they met last month.
Welcoming McGregor to her team, she said: "@thenotoriousmma welcome to the team ,so happy to have you on board with this challenge
Was great meeting and training with you!"
The announcement comes just days after McGregor got engaged to his long-term partner Dee Devlin.
The recently retired MMA star announced the news on social media this afternoon by posting a photo of Dee showing off a diamond ring.
He posted: "What a birthday, my future wife!."
