Jay Z and Beyonce's On The Run II tour concert in Atlanta on Saturday night descended into chaos when someone appeared to run onto the stage and try to chase after the famous couple.

In footage shared on social media by shocked concertgoers, the superstars were just wrapping up a song at the end of the show and disappeared from view when someone can be seen trying to run after them.

There's at least 10 backing dancers on stage still performing their routine, and they don't realise what's happening at first.

As soon as they do, they stop dancing and appear to chase after the stage invader and try to tackle them before the couple's huge security team gets involved.

The end of the video shows a group of security guards holding someone down as the stunned crowd inside the Mercedes-Benz Stadium looks on.

Beyonce’s fans soon took to Twitter to ask how they managed to get so close to their idol.

“I can’t believe that 'fan' walked on stage like that like wth,” one wrote. "Where was Beyoncè and Jay-Z security and wth were the security working at the venue? So many questions."

A second wrote: "That fan hopping on stage is scary as f**k. I’d be backstage in a blind rage if I was Beyonce and Jay Z. Where tf was security?!"

Beyonce's publicist later reassured fans that the pair were fine, writing: "Thank you to all the fans for your concern.

"They are fine and looking forward to the show tomorrow."

The scary incident comes a few days after the Drunk In Love singer narrowly avoided a nasty fall while entertaining fans in Nashville, Tennessee.

A fan account tweeted a clip of the moment, which they captioned: "Beyoncé almost fell down the stairs and she handled it like the Queen that she is."

Showing the singer ascend a light-up flight of steps, she is quickly seen faltering near the top.

The crowd momentarily gasps before she manages to steady herself.
