Sabrina Carpenter fans claim a woman peed in the crowd at a concert in San Francisco

A Sabrina Carpenter fan made quite an impression at a recent tour stop!

On Saturday, November 9, fans who attended the 25-year-old “Taste” singer’s San Francisco concert at the Chase Center claimed on social media that a woman watched the show from the floor of the 18,000-seat arena followed, “squatted” and urinated on the concrete floor.

In a TikTok video, a concertgoer shares a photo of the alleged puddle of urine on the floor as the crowd parted to make way for the mess.

“Imagine just waiting patiently for sweet angel Sabrina to come on stage when suddenly… [a] “Some random girl squats down, takes off her underwear and pees all over the floor,” the concertgoer wrote.

“At least the audience had a good sense of humor after being cleaned up… 😭,” she captioned the TikTok, which included photos of concertgoers posing with text on their phones: “I got peed on in the pit to see .”SABRINA.”

The TikTok user also claimed in a comment that the urinating woman was kicked off the show. “I have a video of her standing on the puddle and then being made to leave by security,” she claimed.

Another TikTok shared by a concertgoer included an image of a Chase Center employee wearing gloves and wielding a mop.

Chase Center representatives did not immediately respond to PEOPLE’s request for comment on Sunday, November 10.

Despite the alleged pissing incident in San Francisco, Carpenter had an exciting week due to the Grammy nominations on November 8th.

Carpenter received six Grammy nominations, including in the four major categories: Album of the Year (Short and sweet), best new artist, song of the year (“Please Please Please”) and record of the year (“Espresso”). Her album also received a nomination for Best Pop Vocal Album, while “Espresso” also received a nomination for Best Pop Solo Performance.

The “Bed Chem” singer shared videos on Instagram showing her tearful reactions to the nominations from her tour bus. When the nominations for Best Pop Solo Performance began to be announced with Beyoncé and Carpenter, the musician and her friends screamed and clapped.

“Beyoncé and Sabrina Carpenter!” she screamed.

Elsewhere in the reaction videos, Carpenter said, “I don’t know how this is possible” and cried as her friends hugged her.

“We on the tour bus this morning take a shot every time we scream like a headphone alert,” the singer captioned the post. “This is the first year I’ve watched the live stream where I’ve heard my name called! I would be lying if I said I haven’t dreamed of this day my whole life, so I’m full of gratitude – Thank you @recordingacademy :’)).”
