Conor McGregor celebrated National Beard Day on Saturday by posting a message online.
The Notorious has been soaking up the sun in Southern France in recent weeks ahead of competing in a gruelling 180km challenge across the Mediterranean.
The Dubliner shared a photo of himself on a boat on his Instagram account with the comment: "Some men make the choice to shave. Others make the choice to be Men."
McGregor also posed for photos with fans over the weekend as he shared the snaps on his Instagram story.
The recently retired UFC star will take part in a water biking contest next weekend.
He will be on the Princess of Monaco's team for the race, which begins in Corsica on September 12 and finishes at Monaco's Yacht Club the following day.
Sharing training pictures online recently, McGregor commented: "Another day closer to #TheCrossing!
"Great work today with her highness Princess Charlene of Monaco!
"Training between the elements of night and day to prepare for our 180km voyage from Corsica to Monaco by sea bike. We are estimating upwards of 30 hours for completion. This September 12th!
"We are ready!"
Princess Charlene is both the event's chief organiser and the defending team champion and trained with McGregor when they met earlier in the summer.
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!"
