Adele has used some colorful language to warn her audience not to throw things.

In a TikTok shared by a concert attendee, the singer is seen at one of her Las Vegas residency shows, discussing a wave of recent incidents in which objects were thrown on stage.

In some cases there were injuries after the objects hit the artists.

A recent notable example was Bebe Rexha who got some serious facial bruises and stitches after being hit in the face by a mobile phone.

Adele said people seem to be “forgetting [expletive] show etiquette” and called for an end to throwing things at the artistes.

Also speaking out was Charlie Puth, who was more diplomatic with his words.

He said, “This trend of throwing things at performers while they are on stage must come to an end. It’s so disrespectful and very dangerous. Please just enjoy the music I beg of you…”
