Katy Perry faces backlash from American Idol fans.

American Idol fans criticized Katy Perry for "tricking" contestants into thinking they were being sent home during Sunday night's episode. Perry told various Top 24 singers they weren't going through to add "extra drama," before revealing that they were in fact successfully continuing onto the next round. Viewers took to social media to voice their displeasure with the "mean" tactic, with some calling it "psychological warfare."
