The world's eyes are on Conor McGregor and Floyd Mayweather as both men gear up for the sporting event of the year, but The Notorious one still has priorities elsewhere.

In a break from training, McGregor took a trip to visit sick children at Crumlin's Children's Hospital in his home city of Dublin, Ireland.

Conor's Twitter feed is normally full with tongue-in-cheek attacks on Floyd Mayweather or shots of him training, but for a few hours on Sunday, it was full of retweets from overwhelmed parents who were happy that their kids had been treated to a surprise visit from the fighting pride of Ireland.

It looks as if Conor made the trip to the hospital completely by surprise and didn't tell the families – or any media – that he'd be making the trip.

Conor beats Floyd in the popularity stakes, hands down.
