The outpouring of love comes as those who were in the club at the time have spoken of their terror at the shooting in which people began to drop to the floor.
Mobile phone footage from inside the scene captures the sound of a gun going off.
Eddie Justice, who was in the club at the time texted his mum from being trapped inside the bathroom to tell her he loved her. He was later killed along with 49 others including the gunman in a day that will be forever remembered as America's deadliest shooting.
Emotional tributes from world leaders have been flooding in following the attack.
President Obama had to deliver a speech following a shooting for the 18th time and used the event to remind Americans about the need for gun control in an inevitable debate that occurs every time there is a mass tragedy in the country.
"The shooter was apparently armed with a handgun and a powerful assault rifle. This massacre is therefore a further reminder of how easy it is for someone to get their hands on a weapon that lets them shoot people in a school, or in a house of worship, or a movie theatre, or in a nightclub," he said.
"We have to decide if that's the kind of country we want to be. And to actively do nothing is a decision as well."
