Humiliating moment Celeste Barber poses next to poster advertising her standup comedy show… but no one knows who she is

Celeste Barber has documented the moment she was left red-faced after posing next to a billboard for her stand-up show in Las Vegas.

The Australian comedian, 42, posted the embarrassing clip on Instagram Stories on Saturday evening after her comedy show Backup Dancer at The Summit Showroom at The Venetian Resort.

The video started with Celeste standing awkwardly next to a screen flashing her poster outside the Palazzo casino and hotel in Las Vegas.

Dressed in a red bikini top, blue button-down shirt, matching shorts and sunglasses, the internet sensation started looking around to see if anyone had noticed that she was the woman in the photo.

Unfortunately, no one seemed to care as many people walked past Celeste, not knowing that she is famous.

Finally, the screen flashed to another poster, prompting Celeste to sheepishly walk up to the camera and sigh, “Not my target audience.”

Celeste took the chilling experience to heart and captioned the video: “Two rules of comedy: timing, reading the room.”

She then travels to Denver, Colorado, to perform at the Paramount Theater.

Backup Dancer “promises to tackle a range of big political topics, from nipple liberation and inappropriate texting of therapists, to what it would be like to be Taylor Swift’s backup dancer,” according to a press release.

“I’m excited to tell some jokes, relive some uncomfortable memories and make my way across the stage with my new show,” Celeste said.

Celeste will tour New Zealand and Australia in August, performing for the first time at Christchurch Town Hall, Christchurch, on August 2.
