Paris Hilton has alleged she experienced "continuous torture" while attending Provo Canyon School as a teenager.
The 39-year-old socialite and DJ was sent to the school - which focuses on behavioural and mental development - for almost a year when she was 17, after she kept sneaking out to parties against the wishes of her parents.
Paris has accused the school of abuse, claiming the teachers would "scream" in her face on a daily basis.
She said: "I knew it was going to be worse than anywhere else. It was supposed to be a school, but [classes] were not the focus at all. From the moment I woke up until I went to bed, it was all day screaming in my face, yelling at me, continuous torture."
Paris also alleged the staff "bullied" her and said "terrible things" about her to her face, and even claimed there were times they would be "physically abusive".
