Two dudes in the porn biz got physical on camera at the Adult Video News Awards in Las Vegas — and we don’t mean sexually … they clashed in a violent incident now being probed by the police, TMZ has learned.

Jay PlayHard, an adult-film content producer, got into a heated argument with porn star Kendra Kox‘s husband — who goes by his nickname “Stayready” — at the January 25 event inside the Virgin Hotels Las Vegas, according to police and witnesses.

Cops say the dispute soon turned into a physical altercation … and it’s now a Vegas Police battery investigation.

Video obtained by TMZ shows Stayready walking up to PlayHard in the casino and saying something to him — then throwing a punch that appears to connect with PlayHard’s head. The two give each other a piece of their minds … but eventually they stop feuding and go their separate ways.

Other footage shows a security guard stepping up to PlayHard, who talks about calling the police.

TMZ interviewed Kendra — she’s best known as a “Naughty Hot Wife,” and owns the porn company Girls Gone Wireless with Stayready. She tells us the reason her hubby socked PlayHard is because they believe he’s stealing their content and others in the industry.

Jay PlayHard — who worked with Kendra as a content manager between 2022 and 2023 — tells TMZ her claim is a case of defamation, and says she’s trying to intimidate him by dragging his name through the mud. He gave a formal statement to the Las Vegas Metropolitan Police Department about the AVN altercation.

Brian Gross, a rep for the AVN Adult Entertainment Expo, says they’re currently working with Virgin Hotels security and local law enforcement, and declined to comment further.

The uncomfortable scene all unfolded just before the Vancouver vs. Detroit tilt at Rogers Arena on Sunday night … as Canadians voiced their displeasure with recent Donald Trump tariffs while Agasha Mutesasira was crooning “The Star-Spangled Banner.”

Mutesasira told us, fortunately, she didn’t take anything personally … revealing the team and others had told her there was a strong possibility it could all happen following Trump’s decision.

As for how her confidence is following the awkward situation — she said it didn’t negatively affect her one bit.

“I knew it wasn’t personal,” she said.

Yet another scary plane incident has left travelers rattled in the U.S. … this time, 2 jets collided with each other on the tarmac at Seattle-Tacoma International Airport.

A Delta spokesperson tells TMZ … Wednesday morning, Delta Flight 1921 from Vancouver touched down for a layover and collided with a taxiing Japan Airlines plane.

According to the rep, the Delta plane — a Boeing 737 carrying 142 customers on board — was in the middle of de-icing when it made contact with the other airplane’s wing tip.

The Federal Aviation Administration issued a statement, claiming the right wing of Japan Airlines Flight 68 struck the tail of the Delta plane at about 10:40 AM PT … and the “aircraft were in an area that is not under air traffic control.”

Some incoming flights were temporarily paused following the collision … though, a rep for the airport tells TMZ the situation has had a “minimal impact to airport operations.”

One passenger, named Jackie Patton, told North Shore News the ordeal was jarring, with a loud “scary” noise and a few seconds of shaking. She added … “Everyone had a shocked reaction. No one knew what had happened.”

Jackie said she was already afraid to fly after the recent aviation tragedies in Washington, D.C. and Philadelphia … 74 people died in the separate crashes.
