Zach Bryan has a simple rule for his shows: “Don’t throw s—!”

Footage from the “I Remember Everything” singer’s Tacoma Dome concert in Washington last weekend surfaced online after a fan recorded the 28-year-old interrupting his performance to call out an unruly individual.

Bryan was playing on stage with another guitarist when an unknown object was thrown at them, hitting the singer’s guest on the leg.

After picking up the object, the country singer shot a glare in the direction it came from as he walked up to the microphone to make an announcement.

‘Who threw this? Who was it?” Bryan asked as he held up an object. “Does anyone know?”

The “Something in Orange” singer asked a few more times, but to no avail.

He gave it a few moments to see if anyone would come forward, or if others would point out the person. Unable to find the person, Bryan instead issued a stern warning.

“Don’t throw s— at concerts, huh?” he said.

“And if you guys know who threw it, you need to get them out of here if we ever find out who did it,” he continued before resuming his show.

While it was unclear why the fan threw the item on stage, Bryan has been dealing with backlash lately over his breakup with ex-girlfriend Brianna “Chickenfry” LaPaglia.

Shortly after the singer announced their split on Oct. 22, the 25-year-old influencer claimed in a Nov. 7 episode of her BFFs podcast she presents along with Dave Portnoy and Josh Richards that Bryan abused her during their relationship.

“The last year of my life was the hardest year of my life dealing with the abuse from this guy,” she said.

“I’m still scared now because I’m scared of him,” LaPaglia continued. “My brain has been rewired and I’m afraid of making him angry. Last week I didn’t want to talk about it because I was afraid.”

A week later, Bryan had not responded to her public comments, prompting her to call his silence on her abuse claims “deafening” during an episode on her podcast.

Later in the conversation, she added, “I obviously think he’s not responding because if he wants to respond, he has to deny it. And if he denies it, I’ll be the full story, I’ll post all the videos and recordings.
