Anthony Joshua handed out wads of cash to people at the Meriden Estate in North London.
Joshua is back in the UK and in the gym following his crushing championship defeat to Oleksandr Usyk last month.
He failed to reclaim the world heavyweight titles, losing a split-decision in Jeddah, Saudi Arabia.

But 'AJ' could return to action in a blockbuster bout as talks are underway for a clash against WBC title holder Tyson Fury.
He's training ahead of a proposed all-British showdown and took time out of his day to spend some time with fans in his local estate.
The 32-year-old shared a video of himself in dialogue with youngsters at the Meriden Estate.

He was filmed taking pictures and greeting them, before shadow boxing in front of a crowd in a car park.
The former world champion then took a wad of cash from his bag and began handing money to a group of people.
Joshua could be in line to receive a massive payday if his bout against Fury comes to fruition.
The self-proclaimed 'Gypsy King', though, has told his rival to sign the contract by Monday.
Speaking to his promoter Queensberry, he said: "We'll know by Monday anyway [if the super-fight is on] because if it's not done by Monday I'm moving on.

"I was optimistic about three weeks ago but it shouldn't be taking this long to sign a contract.
"I'm not waiting around for some guy who's lost three of his last five fights. He's lucky that I'm giving him a world title shot. If not he'll have to wait a long time to get another one.
"I don't mind chucking him a bone. But I don't want him to start dictating [stuff] to me. He is an invited guest at my party. My rules. So if you want to play the game, come to the banquet and take your seat. If not, go to your own banquet."
