Adele has always been known to speak her mind, and she does it on stage as well.

On the day of her recent "Weekends With Adele" residency in Las Vegas, the British superstar was busy throwing goodies at the crowd with a T-shirt gun.

Noticing this trend, Adele warned the audience that such behavior was ~not~ acceptable to her.

"Did you notice how everyone is now forgetting show etiquette and throwing shit at the stage?

Then she joked. I'm going to kill you," she joked.

You may remember from the beginning of this article that Adele was in the middle of shooting t-shirts at the audience during this monologue, but the irony was lost on her.

She said, "Stop throwing things at artists! It's totally backwards; I have to go return the gun on the T-shirt."

She concluded, "I'm not going to throw things at you. Can you imagine?

This was after Eva Max was slapped by a fan on stage and Beebe Lexa was hit by a fan's flying cell phone and had to go to the hospital.

Kelsea Ballerini also recently walked off stage after being hit by a fan's bracelet, and Pink had human ashes thrown at her by someone while performing in London.

Let's not do this. Damn it.
