Britain's Got Talent viewers asked for the show to do something about the screaming coming from the live audience on Thursday night, claiming it was putting them off watching.
Many viewers called for one 'shrieking' woman to be kicked out of the venue, suggesting she was "ruining" the show with her constant screams.
Every time an act finished their performance, or any time the judges or hosts Ant McPartlin and Dec Donnelly stopped talking, the mystery audience member began shrieking.
The screaming was so high-pitched it could be heard over the usual cheering, and it did not go down well with viewers.
Taking to Twitter, fans begged for the show to remove the audience member from the studio or warn her to stop.
The tweets came in right through the show, from the very start and right up until the result was being announced.
So if anyone there did call out the behaviour, it was ignored as the screaming continued for the entire episode.
Calling it out, one viewer said: "No need for it they should of thrown her out tbh I’m sorry it’s spoilt it."

Another fan wrote: "Guys- we know your tracking the socials. Please read the room and deal with the f***ing screaming.
"It’s turning people off and it would be a shame if you lost ratings and advertising revenue because the show was ruined by the relentless screeching."
A third viewer agreed: "Can the screaming banshee shut the F**K UP," as a fourth said: "Malakai is amazing... the woman in the audience however.... is not... why has nobody told her? Ruined the show for me."
Another moment called out by fans was the judges buzzing magician Kimoon Do, with Simon Cowell apologising.
One viewer tweeted: "The judges were so rude to the magician, buzzing in the final they put him there."
Another said: "Buzzers for the magician on #BGT was appalling...so rude!"
A third viewer added: "What's with judges on #BGT buzzing out Kimoon Do? Why wasn't there a camera above the table projecting on to a big screen? You know, like all slight of hand magicians have. Even Cowell said it was not his fault, but they still buzzed. Terrible judging."
Meanwhile a fourth said: "Vote for kimoon do #bgt it wasn’t his fault the production people did him a disservice!!! He’s such a good magician!"
Britain's Got Talent's live semi-finals air all this week at 8PM on ITV1 and ITVX.
