I wasn't one of those girls who always dreamed of being an actress. I went to a normal school and then these film auditioners turned up when I was nine. Then I just fell into this whirlwind.

In Cancún, I felt like I had walked into an American teen movie.

I've never wanted to grow up too fast. I wanted to wear a sports bra until I was 22! ... The allure of being sexy never really held any excitement for me. I've never been in a terrible rush to be seen as a woman.

The most embarrassing one is that I had no idea - and please excuse me - that you guys call a condom a rubber. My version of a rubber is an eraser. I've done that - very loudly asked for a rubber and people have given me strange looks. That was embarrassing!

I went from being totally unknown and never acting professionally to being in a major movie and being very famous. It all happened so quickly, I didn't have any time to work things out. It's been pretty scary at times.

A lot of children of this generation have their entire lives made public before they have a say about what they would want. I think it should always be a choice. I love social media, and I love what it can do and how it brings people together, but used in the wrong way, it's incredibly dangerous.

In terms of men I fancy, I think the actor James Franco is gorgeous. But I find it odd to be described as a sex symbol myself.
