DEMI LOVATO and NICK JONAS took their tour to Orlando on Saturday night, and they gave about 30 employees of the Pulse nightclub a VIP experience, including a meet-and-greet. They also got to watch the show from a private suite. During the show, Nick and Demi said a prayer for the victims, then brought ANDRA DAY onstage.  The three of them sang “Rise Up” together . . . while the names and ages of the victims from the shooting were shown on the big screen.
