The 24-year-old recently spoke out about the British monarch in an interview in Esquire magazine and said she has 'no idea what is going on' when she is 'wheeled out' at the Royal Variety Performance.
She wrote a message on her website saying: "I am deeply sorry if my comments about Her Majesty the Queen caused offence. I am honoured to have met her and have an enormous amount of respect for her and what she does.
"After seeing those words in print, I realised how foolish I was to make such flippant remarks to a journalist. I find it difficult to remember even making them.
"My only defence is that I never expected a respected publication to sensationalise my words out of context like this."
