Adele has warned concertgoers about throwing things on stage after a spate of recent incidents.
In a video posted on Instagram by a concertgoer, the 35-year-old singer had a special message for her fans, which she delivered as she paced the stage with a t-shirt gun in her arm.
Adele, performing at her Weekends with Adele Vegas residency, asks the audience in the footage:
"Have you noticed how people are forgetting f***ing show etiquette at the moment, they're just throwing s*** on stage. Have you seen that?"
"F****ng dare you," she added.
"Dare you to throw something at me."
Adele then jokingly shot a t-shirt into the audience and said people should "stop throwing things at the artist... when you can shoot things at the audience".
'Artists are already so vulnerable'
The recent incidents of fans throwing things on stage and at artists have led to discussions on concert etiquette across social media.
It comes after a fan threw their mother's ashes on stage at a Pink concert during the BST Hyde Park festival.
The singer was left stunned mid-performance as she hesitantly picked up the bag of human remains and placed it back down after realising what it was.
At a Bebe Rexha concert, the singer was left with a bruise after a man threw a mobile phone at her face during her performance.
Video footage shared online from the gig at The Rooftop at Pier 17 in New York showed the phone hitting the star on the forehead.
She then stumbled backwards and put her hand up to her face before turning away from the audience and falling to her knees.
The singer was then taken to hospital for treatment and was left with redness, swelling and bruising.
In another incident, country singer Kelsea Ballerini also had to stop mid-performance after a concertgoer threw an unknown object at her face.
The fan who posted the video wrote on Twitter and said:
"Guys. I know we all mean well. We all want to show Kelsea love the best way we know how, and shower her with all the gifts. But throwing things on stage where artists are already so vulnerable is NOT the move.
"If you can't hand it to her, there are so many other options. Lord, give it to us! We will make sure it gets to her. But PLEASE don't put her in danger like this. Again, I know you all mean well, but this is becoming a safety issue."
In 2022, Harry Styles was seen waving at the crowd before rubbing his eye as Skittles were thrown at him from the audience.
At the time, Skittles responded and said: "Didn't think I needed to say this: Please don't throw Skittles."
