The 24-year-old star is a close friend of Prince William and was a guest at his wedding to Kate Middleton in April this year.
Asked about the wedding, she said to E! News: 'I had a lovely time. I just went in, sat down, tried to be on my best behaviour. I was very happy to be there. It was like being part of a fairytale.
'Then, I had a really weird lunch with lovely people, but I didn't know any of them. So, after the church I ended up getting totally rat d with like ten people I'd never met before in my whole life. It was brilliant.'
