The 31-year-old star said her dreams of becoming a ballerina broke when she was made to feel like an outsider during her weekly ballet lessons, reported Female First.
"I wanted to be a ballerina. I did ballet from that young. And then I went to the Royal Ballet (summer school) when I was nine or 10. I hated it and squashed the dream. It wasn't me. I didn't fit in.
"I had to be sponsored to go there because my parents couldn't afford to send us there, and everyone else was obviously... Basically I was a bit of an outcast," she said.
"It was the first time I'd ever felt class. I didn't know what it was. Everyone around was normal to me. There was this thing, and we were all on the same level...I didn't understand it. I just knew it was different. And that they were looking down their noses, if you like," she said.
