WATCH: Anderson Cooper’s Emotional Tribute to Victims of Orlando’s Nightclub Shooting

Anderson Cooper, Tituss Burgess, Prince William and more gave heart-wrenching tributes to the victims of the Orlando nightclub massacre, the largest mass shooting in American history.

Cooper broke down as he read all 49 names of the victims, who were killed at Pulse nightclub on the morning of Sunday, June 12. He fought back tears as he told a little bit about each person as told by family and friends in the more-than-seven-minute segment, which also featured pictures.

“They are more than a list of names. They are people who loved and who were loved,” the CNN host said.

Unbreakable Kimmy Schmidt’s Tituss Burgess also gave a touching tribute through song while at a rally outside New York City’s historic LGBT landmark the Stonewall Inn. He sang “Somewhere” from West Side Story to the huge crowd, absolutely slaying it:

Burgess told the crowd, “I have to tell you, being here and seeing all of your faces has comforted me in a way that I did not expect coming down here. I am indeed Orlando, and in times like this, I find myself at a loss for what to do.”

Nick Jonas also was present at the Stonewall rally, and he addressed the crowd saying, “More than anything, I just want to speak from the heart and say I woke up yesterday to the news, like all of you, and my heart broke.”

He continued:

I grew up here in New York City and New Jersey, performing on Broadway shows, surrounded by some of my closest friends from the LGBT community. My father, a minister from New Jersey, shaped my view that love is love, that we are all equal. That no matter who you are, or where you’re from, or where you’re going in life, you have the right to love and be loved. So yesterday, thinking about the families of the victims and the lives lost, I just thought that could be my friend. That could be my people.

Meanwhile in London, England Prince William and Kate Middleton gave a somber tribute to the victims while singing a book of condolences at the American Embassy. Prince William wrote, “With our deepest condolences and with our thoughts and prayers to all those affected.”
