Don’t wait run fast.

A fan faceplanted after falling through a hole in the stage during Machine Gun Kelly’s concert at The O2 Arena in London on Thursday night.

As seen in a video shared on TikTok, a concertgoer, who was on stage while the “Starman” singer was performing, was dancing and clapping her hands before she accidentally missed the large gap in the floor and stepped right into it. MGK turned around as she plunged through the stage.

The fan seemingly hit her face on the edge of the stage as she went down, too.

MGK, whose real name is Colson Baker, screamed, “Oh my god, hold on,” as he reached down to help her out. Keeping in tune with the song he was performing, the artist added, “I really hope you’re fine.”

Other audience members on stage also rushed to help pull the woman up.

“Are you okay?” MGK asked, to which she seemingly said yes.

“You are?” continued the Grammy nominee. “Let’s f–king go!”

Luckily, the fan quickly recovered and continued singing and dancing.

After the song ended, the fan tried to apologize for the mishap, to which MGK responded: “Oh, dude. No, no, no. Sorry? That was the coolest thing you could have ever f–king done.”

“This is the first time I’ve ever sold out The O2. That was the first time anyone has ever fallen off the stage, dude. Let’s f–king go,” he continued before the pair hugged.

The hitmaker then gifted the fan his hat before she left the stage with a massive smile on her face.
