Unusually for rent-a-gob Katie Hopkins, she failed to stand her ground last night.

The former Apprentice star and Sun columnist was appeared on the X Factor companion show the Xtra Factor was was asked her opinion on popular eight-member boy band Stereo Kicks.

And when Katie is asked her opinion, she does not hold back!

The 39 year-old was asked which of this year’s acts were not her cup of tea and straight away she identified the boy band created for the show from individual auditionees:

“Stereo Kicks, can’t stand them. Eight people, why do we need eight? They stand in a line like they’re waiting for a bus.

“They look like teenage boys waiting at an STI clinic to find out some really bad news. ‘Oh my God, what have I caught, who have I slept with, what have I caught?'”

However, Ms Hopkins was not prepared for what happened next.

The families of the boys – especially their mothers – hit back at Katie Hopkins, shouting, screaming and yelling abuse at her. A source at the Xtra Factor told The Sun: “The families began shouting and hurling abuse. One of the mums was right up in her face, saying that she looked like a horse and was despicable. One of them asked how she’d like it if people abused her children.”

At this point and seeming “rattled,” Katie left the studio. The source said: “Katie was rattled – and in the end security and her own chaperone sneaked her out the back way. She is tough, but even Katie was rattled by their reaction. She said afterwards that it was far more intense than most of the backlashes she has faced in the past – yet Katie also admitted that it was probably fair enough.”

Katie downplayed the incident on her Twitter account today, saying: “Stereo Kicks lynch mob of mums had a right to have their say. All lower order animals attack to defend their young. And this lot were hairy.”
