At an otherwise joyful celebration of Wicked in Singapore for the second film's Asian premiere on Thursday (Nov. 13), a scary moment took place when someone in the crowd charged at Ariana Grande and forced Cynthia Erivo to step in as her costar's bodyguard.

In video of the incident captured at the event, the two leading ladies walk the red carpet at the event alongside Michelle Yeoh, who also stars in the Wicked films, when a man suddenly jumps over the barricade and runs directly at Grande. After reaching the pop star, he forcefully puts his hands on her shoulders and wraps an unwanted arm around her neck, with Grande looking terrified.

Immediately, Erivo springs into action, rushing to tear the man away from Grande while Yeoh makes sure the R.E.M. Beauty founder is okay. Footage from the moments afterward shows three different security officials pinning the aggressor to the ground before hauling him away.
