He said: "What an incredible thing we are doing tonight, would you not agree?"
The scene was picked up by cameras during Justin Bieber's set, and it didn't go unnoticed on Twitter.
He got onstage armed only with his guitar and his voice, and boy, did he use it. "And he loves you, and he's here for you". "Put your hand up if you're not going to let go", he continued, echoing his "Cold Water" lyrics. And I stand with you Manchester'.

Ariana Grande will return to the stage Sunday in Manchester, England, for a concert to raise money for victims of a suicide bombing that struck at the end of her last show almost two weeks ago.
More than 50,000 crowded into Emirates Old Trafford Cricket Ground to watch Grande headline the benefit.
Seven people were killed and 48 were injured in the attack.
The singer, who was welcomed on stage by former Take That bandmate Gary Barlow, flaunted a black sweatshirt from Justin's objective world tour.
A third fan said that Sunday's concert would be "really emotional".
The sold-out "One Love" benefit follows another deadly attack that rocked London late Saturday when three men drove a van into a crowd before stabbing people in nearby bars and restaurants. The show will be broadcast across the globe and proceeds will go to an emergency fund set up by the city of Manchester and the British Red Cross.
"We will not quit or operate in fear".
"There are two large-scale events taking place in Greater Manchester today and we would like to assure people that these will still take place, but with additional security in place to ensure the safety of everyone", Greater Manchester Police Assistant Chief Constable Garry Shewan said in a statement on Sunday. "We won't let hate win", Grande wrote in a statement when she announced the benefit concert last week.
