It's been three weeks since the horrifying June 12 attack on Pulse Nightclub in Orlando, Florida which left 49 people dead, but we're still feeling the emotional shockwaves from the tragic shooting — and it's unlikely that the feeling will go away anytime soon.

Like us, devastated celebrities are still pouring their hearts out for the victims, especially within the music industry: On Saturday July 2, Demi Lovato and Nick Jonas hit up the Amway Center in Orlando while on their joint Future Now Tour, and together the two singers teamed up for a heartbreaking tribute to those lost and affected by the shooting that wracked the town last month.

Lovato and Jonas first shared a touching prayer with the audience before inviting Grammy-nominated artist Andra Day onto the stage.

"This song is incredibly inspiring, and she is incredibly inspiring," Nick said as he introduced the singer-songwriter, describing her as a "dear friend."

While the headliners sang backup, Day dedicated her uplifting R&B hit single "Rise Up" to the victims. As the three performed, all 49 names of those murdered at Pulse — as well as the name of The Voice finalist Christina Grimmie who was shot to death on June 11 — scrolled on a screen behind the them in a touching display of solidarity and mourning.
