The 'Equals' actress - who previously dated her 'Twilight' co-star Robert Pattinson and is now rumoured to be in a relationship with her assistant Alicia Cargile - no longer pays too much attention to other people's advice as she just wants to "do her own thing".

She said: "I'm a lot happier and I'm feeling really good.

"I feel I can be myself more and now allow myself to get sidetracked by other considerations or advice from people.

"Earlier in my career I had too many people telling me what I should be doing and it was hard for me to deal with all that.

"That was very confusing because I've always been the type of person who likes t do her own thing.

"But when your career reaches a certain level, there are so many responsibilities that come with that and sometimes you feel your life is not your own any more.

"That's why I decided to change a lot of things about how I was working and try to be true to myself."

The 25-year-old actress is proud she has been "able to make sense" of what she wants from life at a relatively young age.

She added to Diva magazine: "It's important to understand as soon as possible what you really want in life.

"Some people never figure that out but I think I've been able to make sense of what I want to accomplish and how I want to live... The most important thing is to be really happy."
