"Do you guys smell gas? It's pretty intense," Katy says in a teaser clip for the episode, as Luke agrees, "We're getting heavy propane."
"I have a slight headache from it," Perry adds, as she stands up to leave the studio and production begin evacuating the crew and contestants. "Oh, it's bad. It's really bad."
The clip shows the fire department and ambulances arriving on the scene, and the judges remarking that they can still smell gas from outside.
"This is not a joke, there really is a gas leak," Bryan confirms, approaching the fire truck, as "Dark Horse" star Katy tumbles to the ground from a crouched position after admitting, "I'm not feeling good."
Last November (2019), officers from the Sunriver Fire Department shared videos and photos with the Idol coaches after they attended to the incident, which ended up being a problem in the kitchen at the Sunriver Resort.
The full ordeal will play out in Sunday's (February 23) instalment of the show.
