While performing a show at London's O2 arena on Saturday, Billie Eilish briefly paused her set after learning that several fans got into difficulties in sweltering temperatures.
"Are you all ok?" she asked. "People were fainting and getting pulled out. It's hot, I know". After fans said they were "squished", she halted the music until the pressure in front of the stage eased.
"Take a step back, give everybody some space," Eilish said. "If someone looks a little woozy, just tell someone." She added: "Don't try to save feelings."
