The 28-year-old bore the brunt of the anger of many Twitter users after Sunday evening's episode, which featured a "home-coming" segment in which the remaining contestants visited their former schools and neighbourhoods.
While visiting her school throngs of pupils stormed to the car Tenyane was in, forcing her to stay in her car to avoid the commotion.
She could also be heard telling the scholars: "Okay, guys, I'm going to come out of the car, but don't jump on me, okay? I will literally fall".
The knives came out for her after that comment.
One Twitter user said: "I'm glad Tshidi is gone! She was too much of a prima donna!
"She deserved de boot! Now she can learn 2 respect her fans!"
Tenyane said: "Standing there in front of 2,000 pupils who took 20 minutes to calm down got me very scared. It's a pity it was taken out of context.
"But the most hurtful thing is that people were calling me a b***h and said I was disgusting.
"The very same people, mind you, were older than me and they were supposed to be my parents."
Idols season 7 top 6 finisher Kelly Fortuin wasn't surprised. She tweeted : "So again my prediction was correct!! Due to a insert being edited the way they wanted ppl to view her!! This happens every year!!.
Fortuin joked that if she were to release a debut album, it would be titled Diva, with a lead single called Don't Jump on Me.
The Top 3 is now Khaya Mthethwa, Monde Msutwana and Melissa Alisson.
This season's winner will be announced on October 2.
