Kristen Stewart is ''f***ing proud'' of the 'Twilight Saga'.

The 24-year-old actress understands why people ''talk s**t'' about the vampire franchise - in which she starred as Bella Swan opposite ex-boyfriend Robert Pattinson as Edward Cullen - but she will always defend the project because it had such a ''pure'' intention.

She said: ''It wasn't entirely cohesive. We ebbed and flowed. I will definitely acknowledge that. But the intention is so f***ing pure in a weird way.

''Anybody who wants to talk s**t about 'Twilight', I completely get it, but there's something there that I'm endlessly, and to this day, f***ing proud of. ''My memory of it felt - still feels - really good.''

The 'Still Alice' star finds it frustrating that she is only viewed as a ''real, serious actor'' if she isn't appearing in blockbuster movies.

She told Patti Smith for Interview magazine: ''I'm always asked about what type of things I want to do, and if I make decisions based on my last project. Say I do a big franchise movie about a vampire that falls in love with a normal girl. It's like, 'Now do you want to show them that you can be a real, serious actor?' It's like, 'Was I not being a real, serious actor?' ''

When she isn't acting, Kristen likes to write and paint but has no desire to make her art public because she doesn't want it to be ''trivialised''.

She said: ''I start to lose my mind if I'm not working on something, like breaking my back on something.

It's also very counterintuitive to boil down something so personal, something that requires privacy. All of a sudden, you open it up to the world and put it in a context where you could easily trivialise what you've done.

''If people sense that discomfort, they're not wrong. It feels weird. It feels unnatural because, suddenly, on a dime, you turn around and go, ''Okay, I'm going to let everyone into this [work]''
