The 'RIP' singer went to the Sylvia Young Theatre School in London, where she studied music. However, according to Ora, following the rules at the prestigious establishment was a constant difficulty.
She told more! magazine: "I was cheeky. I hated wearing a hairnet. Sylvia would come into ballet class and catch me without one. 'Rita, there are some rules. This is a serious matter', she'd say."
Despite her problem with rules, the 21-year-old still looks back at her time on the school fondly.
''[Sylvia] had a soft spot for me, though," she added. "I was never rude, I just wasn't great at listening.
''When I left Sylvia's at 16, I thought I'd be famous a week later. I got slayed... I got really confused and thought I'd messed up. When you don't know yourself, you think everyone else is right. So you cry.''
Ora recently did a stint as a judge on The X Factor, and has said that she would be thrilled to return to the show.
