The 22-year-old singer displayed the names of the 49 people, who were killed by a gunman at gay nightclub Pulse, and the words "#OrlandoStrong", on a big screen behind him while he sang his song 'Purpose' during his gig in Orlando, Florida.

And Justin also showed his support by telling the audience: "You've been through a lot here, and my heart goes out to all the families. You can't take down Orlando!"

Justin later tweeted the "#OrlandoStrong" message and wrote: "Thank you for tonight. Don't ever be afraid to be yourself. #OrlandoStrong (sic)."

Justin is not the only celebrity to publicly declare his support for the victims, with Lady Gaga joining thousands of people outside City Hall in downtown Los Angeles after the attacks, where she helped to read out the names of those who died.

She said: "As we have now witnessed the largest mass shooting in American history, I can't help but feel that this level of hatred, like all prejudicial crimes, this is an attack on humanity itself."

Nick Jonas and Tituss Burgess were among those who gathered at a vigil in New York while Mara Wilson took to social media to reveal her sexuality as "bi/queer" in the wake of the mass killings.

Madonna called for an end to "hate crimes" and declared her support for the victims, posting an image of two men touching tongues on her Twitter account.

Underneath the picture, she wrote: "Love is love. Stop hate crimes. Any form of terrorism is a form of Hate! (sic)"

And Kim Kardashian West made an impassioned plea for better gun control laws.

Kim said the current legislation "makes it easy for dangerous people" to obtain weapons.

She tweeted: "I'm truly at a loss for words. To everyone in Orlando affected by this massacre, my thoughts, love, & prayers are with u.

"Under current federal law people on terror watch lists can legally buy guns -- this is called the Terror Gap.

"We have repeatedly called on Congress to close this loophole that makes it easy for dangerous people to get guns & kill. Nothing has changed!!!! People continue to senselessly die. When will these gun laws be changed?! (sic)"
