The Valentine's Day beauty claims she has "weird features" that are too big for her "small head" but says that she's learned to live with herself.

She told InStyle: "I think I've got really weird features, I have very large features on a very small head, but I'm not going to beat myself up, it's my face - I'm not very pretty, but that's OK because I look like myself, and I think at the end of the day, as nice as pretty is, authenticity is more important."

The 27-year-old Devil Wears Prada star also said she has to work hard to keep her body in shape.

"If I don't work out at all, I have too much curve and no tone, which is not OK. It's about finding balance," she said.

Anne - who names Tilda Swinton, Gwen Stefani, Lady Gaga, Selma Blair and Natalie Portman as her style icons - has a strong fashion sense and likes to balance a tomboy daytime look with being glammed up in the evening.

She told the magazine: "In the evening it would never occur to me to go out in motorcycle boots like this. I love going out in high heels and dressing up and glamming it up, and having there be a distinction between what happened throughout the day and the evening.

"I like people who are true to themselves."
