Gas overwhelms Perry on set

Pop star Katy Perry tumbled to the ground on being overcome by propane fumes during filming of the American Idol episode to be shown Sunday, People magazine reports. Perry and fellow judges Lionel Richie and Luke Bryan had to flee the studio as firefighters rushed in to determine the cause of the leak. “I have a slight headache from it,” Perry says in a clip. “Oh it’s bad, it’s really bad.” Outside, she collapses, saying “I’m not feeling very good.” The auditions apparently resumed after the all-clear.
