We had fun just messing around and being awkward like they would be awkward. There's always that stage in a friendship when you wonder whether it could be more.

I've never really had any barrier to break I guess. I don't really have anything to rebel against. I'm quite lucky.

The entertainment industry is pretty nuts, and having had that experience outside of it and going to university has really made a big difference. It's important to me to feel like I have my own life.

What I find difficult about photo shoots is the line between playing a character - you're being asked by the photographer to take on a role like you would in a movie - and being a fancier version of yourself. It's about finding that line between being spontaneous and open to direction, but also trying to explain to photographers that the "me" is often taken out of context because it has all of this other stuff attached to it.

I can be 100 years old but I will always be proud to say I was in Harry Potter.
