Mess with her show

Using the watch, you stop time. You find a drink vendor and take a cup of ice cubes and bring it to the stage where you find Nicki paused

You unzip her fishnet body suit and proceed to fill her pussy and anus with ice cubes. You then re-zip her body suit. You use the mind control function on her: "no matter what happens, do not stop your show."

You find a spot in the crowd near the stage and restart time.

Nicki starts to sing then screeches into her headset microphone. She clamps a hand over her crotch. With wide eyes, she stares at the crowd, then goes to start singing again, but her voice is shaky and she loses synch with the music. A pained look crosses her face as she tries her best to continue her song, but she keeps having fits and stops. The crowd starts to quiet a bit as they try to figure out what's going on.
