Jake Paul trolled Conor McGregor and a number of other fighters on Father's Day.
The YouTuber is preparing for a boxing bout with former UFC champion Tyron Woodley, which takes place on August 28.
He shared a montage of fighters Kamaru Usman, McGregor, Daniel Cormier, Ben Askren and Woodley after they had suffered defeats on social media on Sunday.
Commenting on the post, Paul said: "As a father myself, today means a lot to me. even though they’ve all lost a lot… my sons all have made me so proud."
Paul has called out McGregor on a number of occasions, but the Dubliner doesn't seem interested in fighting him.
Speaking to Bloomberg ahead of his January bout with Dustin Poirier, McGregor said: "If they are fighting well then it can't make a mockery of fighting. They're getting in and competing. I am not so much against it.
"What I will say though is the numbers that that show calculated was a Mike Tyson fight. You had an icon fighting as well as Roy Jones Jnr, two GOATs [greatest of all time] of combat sports.
"And then you had the YouTube kid and NBA star competing underneath that. So they done good business.
"Am I into those competitions myself? You know it's not the most high-level - if any level - at that stage.
"Obviously the Tyson vs Jones fight was very high level and very interesting to see what they're like in their older age. I thought they both fought amazingly.
"As they say, if it makes dollars, it makes sense. I know Dana and the UFC are not really into it, but I'm not so against it.
"I think if people are willing to get in and take the risk of making that walk, I'm certainly a viewer."
Paul again hit out at McGregor following his brother Logan's exhibition boxing match with Floyd Mayweather earlier this month, claiming that the former two-weight champion is "ducking" him.
The Notorious faces Poirier for a third time on July 10 in Las Vegas.
