Demi Lovato and Nick Jonas teamed up with Andra Day on Saturday, July 2 to remember the victims of last month's mass shooting at a gay nightclub in Orlando.

Forty-nine people died and dozens were injured when a lone gunman opened fire in the Pulse nightclub.

The trio sang an emotional rendition of Rise Up during their concert at the Amway Center. They also remembered Christina Grimmie, a former The Voice singer shot in Orlando the day before the incident at Pulse.

“Orlando you were incredible last night,” Jonas wrote on Instagram. “Thank you @andradaymusic for helping DEMI and I … honor the victims of the terrible acts of violence recently.”

“I adore you Miami,” Lovato added in a separate Instagram post.

According to TMZ.com, Lovato and Jonas surprised about 30 Pulse employees with tickets to their concert and a meet and greet.
