Despite being just 23, Emma has been in the business for 15 years, and she's confessed in a new interview, she at times regrets starting so young.
"There are all these actresses who have emerged in the last year or two, and they get to emerge as this complete human being. And I'm so jealous!" she told the April 2014 issue of Elle magazine, or which she is also a very glam cover star.
Growing up in the public eye means a young Emma was always conscious of her having a personal life away from the Harry Potter bubble: "I remember reading this thing that Elizabeth Taylor wrote", she explained.
"She had her first kiss in character. On a movie set. It really struck me. I don't know how or why, but I had this sense that if I wasn't really careful, that could be me. That my first kiss could be in somebody else's clothes. And my experiences could all belong to someone else."
