Billie Eilish stopped her own concert in London because 'people were fainting' in the crowd

• Billie Eilish halted her concert in London on Saturday because "people were fainting," per the BBC.
• She paused the music and asked her fans to "take a step back, give everybody some space."

Billie Eilish interrupted her own concert on Saturday to encourage fan safety, according to the BBC.

During the "Happier Than Ever" tour stop at London's O2 arena, Eilish cut the music due to extreme heat and crowd density.

"People were fainting and getting pulled out. It's hot, I know," she said into the microphone, per the BBC.

The 20-year-old superstar implored attendees to "take a step back, give everybody some space" before continuing the show.

"If someone looks a little woozy, just tell someone," she said, adding, "Don't try to save feelings."

Eilish is known for pausing her performances to check on her fans in the audience.

At a February tour stop in Atlanta, she asked her crew to retrieve an inhaler for a fan near the stage.

"I wait for people to be OK until I keep going," Eilish told the crowd in a video published by TMZ.

"Take a deep breath, go get water, whatever you need to do to be happy and healthy right now," she continued. "We're all good, everybody's OK. We're going to keep it going."

Last September, she chastized security guards at Governors Ball music festival in the middle of her song "Everything I Wanted."

"Security, why aren't you paying attention? For real," she said into the microphone during the song's first verse.

After singing a few more lines, she added: "One job."

This came shortly before 10 people died of compression asphyxia during Travis Scott's performance at Astroworld Festival last November. The concert was declared a "mass casualty event" by police about 30 minutes before it ended.

Scott has received heavy criticism for failing to pause his performance or check on fans who needed medical attention.
