For Good’ Singapore premiere, Cynthia Erivo reacts

He threw an arm around the Grammy winner’s shoulders and began jumping up and down as co-star Michelle Yeoh looked on in fright.

Before security reached Grande, Erivo rushed toward the “Victorious” alum and attempted to push the fan away.

The man was then apprehended by multiple bodyguards.

The scary moment was caught in multiple fan videos, with one showing Erivo, 38, comforting Grande in the aftermath.

Social media users praised the Tony winner via X for being “so quick” and “having faster reflexes than multiple grown male security.”

One tweeted, “Security needs to hire Cynthia she was not playing at all.”

Another added, “She said, ‘Not on my watch.’”

The fan, identified as Johnson Wen, has pulled similar stunts with Katy Perry, The Weeknd and more A-listers in the past.

He proudly shared a video of his latest viral moment via Instagram, writing, “Dear Ariana Grande Thank You for letting me Jump on the Yellow Carpet with You ❤️.”

On his Story, Wen gushed that he “finally met Ariana Grande tonight” — then assured his followers he was “free after being arrested.”

Reps for Grande and Erivo have yet to respond to Page Six’s request for comment.

The actresses have formed a strong bond since they began filming “Wicked” in 2022 and made headlines for their affectionate press tour.

“[We’re] insufferable, yes,” Grande joked to Variety in December 2024. “We’re horrible. It’s bad. The most annoying. … Cynthia is just an absolute brilliant gift of a human being.”

As for Erivo, she credited “hard conversations” and “vulnerability” with their close friendship while speaking to Elle the previous month.

In the November 2024 interview, the Broadway star explained, “That’s what makes relationships. Those are the things that make you close.”
