Billie Eilish gave fans a warning as she talked about the "infuriating" and "dangerous" trend of performers having objects thrown at them on stage.

Eilish, 21, has been a victim of the trend for "years" but also understands where the fans are coming from.

"I’ve been getting hit onstage with things for like, literally, six years, I don’t know why this is like new," Eilish said at the world premiere of "Barbie" while speaking to The Hollywood Reporter. "People just get excited, and it can be dangerous."

Eilish's brother and recording partner Finneas noted that the objects most often thrown are phones, and fans want photos.

"It’s absolutely infuriating when you’re up there," Eilish noted.

"I have mixed feelings about it, because when you’re up there it blows," she explained. "But you know it’s out of love, and they’re just trying to give you something. You’re in a vulnerable position, but I’ve been getting hit with stuff for like years."

Both gave fans a stern warning.

"Don’t do it. We get it, but don’t do it," Finneas said.

Eilish added, "Don’t throw things onstage, but we love you; it’s very sweet."

Eilish's comments came just a day after pop star Taylor Swift had friendship bracelets thrown at her as she walked backstage Saturday at Arrowhead Stadium.

The "Midnights" singer seemingly ducked as the bracelets were tossed her way from above. Her security team told the crowd to stop as they tried to catch them or knock them out of the way.

Right before the bracelets were thrown, Swift could be seen in the video waving at fans shortly after finishing her Kansas City Eras Tour stop with her hit song, "Karma," from her latest album.

Swift isn't the only star to have things thrown at her. Harry Styles, Kelsea Ballerini and Ariana Grande have all been hit with items thrown on stage during their performances.
