In the digital era, not even Beyoncé can beat cell phones — her performance in Dubai was caught on camera by several people … despite going above and beyond to keep it secret.

The singer’s down in the UAE, where she’s been booked for a show at (or near) this swanky hotel called Atlantis The Royal …

which supposedly shelled out millions for her services, upwards of $24 million for just a ONE-HOUR set — that’s the word on the street, anyway.

Tons of videos circulated Saturday in the lead-up to her gig, where people who had snagged a seat to the show were reporting that the hotel

and other honchos were demanding people put their devices in locked zip bags — similar to how a lot of comics do these days.

There was also a live feed stream the hotel had up that had been capturing a lot of her sound checks in rehearsal … which was promptly cut off right at the curtain call.

And yet, despite their best efforts — people on the ground were able to film it all regardless. 🤷🏽‍♂️

You can hop into the Beyoncé trend right now on Twitter and see all the footage for yourself — it sounds like she opened with a cover of Etta James’s ‘At Last,’ and then went on to perform a few of her own tracks … like ‘XO,’ ‘Brown Skin Girl’ and other ‘Renaissance’ songs.

Bey was decked out in an elaborate, flowing yellow dress … and the stage design was pretty intricate too — coupled with a live orchestra and an awesome rising run backdrop to boot.
