According to a source, the I Kissed a Girl singer's "rude and condescending" remarks to grieving participants have alienated fans.
Fans are furious with Katy because of how she degraded a singing duo, the insider said, adding that she has previously faced criticism for making harsh remarks.
"She insisted they perform before they had a chance to practice and then criticized their work in front of a national audience as 'underwhelming'!"
After Katy humiliated and insulted 25-year-old candidate Sara Beth Liebe, who ultimately withdrew from the singing competition, there was a recent uproar.
Following Liebe's admission that she was a mother of three, Katy acted as though she was stumbling away from the panel's table as fellow judge Luke Bryan fanning her.
Liebe remarked, "If Katy lays on the table, I think I'm going to pass out."
"Honey, you've been laying on the table too much," Katy snarled at the degraded performer.
Not everyone who was watching liked Katy's crude jab. Liebe eventually quit Idol, but he still tolerated Perry. Others, though, aren't being so kind to the drama queen.
One reviewer commented on Instagram, "Katy is rude and condescending to contestants unless it's a male cutie, in which case she acts like a teenage fool." "Goodbye, Katy."
