Pink was flabbergasted after a fan appeared to throw a bag of their mother's ashes on stage

• Pink performed on Sunday at the British Summer Time festival in Hyde Park, London.
• During her performance, a fan tossed her a bag of white powder, which appeared to be a loved one's ashes.

Pink's performance at the British Summer Time festival on Sunday was interrupted by an unconventional gift.

According to videos shared on Twitter, Pink was in the middle of singing "Just Like A Pill" when someone threw a plastic bag full of white powder onto the stage.

When she bent down to pick it up, Pink asked, "Is this your mom?"

The bag may have been labeled, or perhaps the concertgoer confirmed the question with a nod. But Pink seemed visibly shaken by the exchange, setting the bag down gingerly at the edge of the stage.

"I don't know how I feel about this," she said into the microphone.

This is the latest in a recent string of bizarre interactions at concerts. This month, Bebe Rexha was injured by a phone thrown at her face and Ava Max was slapped by a man who rushed the stage.

Some musicians like Harry Styles have encouraged fan interaction at shows. Many videos show him wearing cowboy hats and feather boas that fans have tossed on stage during his lively Love on Tour performances.

However, the "Harry's House" singer was also injured last year after a fan threw candy at him, pelting him in the eye. Skittles issued a statement condemning the behavior.

It also recalls the debate over "concert etiquette" in a post-pandemic world. Many music fans have expressed concern that enthusiasm has spiraled out of control at live shows, and concertgoers should be more respectful of their peers — and of the artists who are performing.

A representative for Pink did not immediately respond to Insider's request for comment.
