London, UK - Billie Eilish had to stop her show in London's O2 arena this weekend after fans began to struggle with the hot temperatures.

The singer briefly paused her performance on Saturday night to check that fans were "all OK" as they were getting squashed at the front of the stage.

The 20-year-old urged people to "take a step back" in order to "give everybody some space," and asked the O2 security team to distribute water to the audience.

She said: "People were fainting and getting pulled out. It's hot, I know, it's crowded, it's hot."

"Are you squished a little bit? If someone looks a little woozy, just tell someone OK. Don't try to save feelings."

It is not the first time Billie has stopped her music to allow audience members to be helped. She also put the brakes on a performance in Atlanta this February during her Happier Than Ever tour.

The "Bad Guy" singer could be heard saying: "I wait for people to be okay until I keep going," but later denied she was making a reference to the Astroworld tragedy, when a Travis Scott show turned deadly.

Ten people died as fans surged towards the stage during a performance by Scott at the two-day festival in Houston, Texas, in November.

Eilish's O2 show is part of a string of British tour dates which will also take her to the SSE Hydro in Glasgow and Birmingham's Utlilita Arena.

On Tuesday, the singer treated fans to a performance of her as-of-yet unreleased song TV with her brother and co-writer Finneas O'Connell at Manchester's AO Arena.
