I'm a bit of a workaholic. When I feel like I'm not doing something, it drives me insane.

You need to keep everyone wanting more. Every character has so much depth, and there was so much thought that went into it, but it would've taken away at some point from the main story, and everything I think kind of was woven together really beautifully, so that you cared about everyone, and everyone had their own story, but everything helped the main plotline.

I've definitely learned more about myself through experimentation over the years - which products work best for my skin and tricks from various makeup artists I've been lucky enough to work with.

I just finished 'Butter' for Weinstein, a comedy with this incredible cast - Hugh Jackman, Olivia Wilde, Alicia Silverstone - all-star cast and it was a fun set to be on. I've gotten really lucky to get all these down-to-earth cast members. 'Butter''s about butter carving in Iowa.

I've just decided that I have to continue to live my life and do what I do. Hopefully, people love me because of who I am, not who I pretend to be.

Throughout the course [of Twilight], you get to see a little more of her vampiric side, because I think she's this vampire with a heart of gold and so that was kind of fun - to show her be a little tough and a little fierce, and to show that she has a little bit of a sassy side when she's dealing with the wolves or with Jacob. So I feel like I got to really round [Alice Cullen] out quite nicely.

You can't control the paparazzi. But if you go to Coachella you're going to get photographed. Whereas if you're at home, walking down the street you probably won't. It's something I've learnt to navigate my way around but I try to keep my private life private.
