Kristen Stewart has enrolled at university in Los Angeles.

The 23-year-old star left school at 13 to pursue her acting career, but is now preparing to return to education by studying English Literature at the University of California, Los Angeles (UCLA).

A source told the Daily Mirror newspaper: ''Yes, Kristen's a Hollywood actress worth millions but she is already considering a life after film. She never got to complete college and she wants to get a proper education.''

'Twilight' beauty Kristen - currently shooting war film 'Camp X-Ray' - will juggle her acting career with her studies.

The source added: ''She is a voracious reader and cannot wait to get going on her correspondence course.

''It won't be easy and it will mean putting in some fairly strenuous hours. But once she's graduated, Kristen will be able to do almost anything she wants, in or out of Hollywood.''

UCLA is one of America's most respected universities with its English course considered among the best in the country.

Kristen has previously said she had no regrets about leaving school as a teenager to be home schooled on film sets, because she got such a hard time from other students, many of whom didn't even know her.

She has said: ''I was glad to leave school. I was missing a lot of classes and they were failing me.

''I couldn't relate to kids my own age. They are mean and don't give you any chance. Once you have done with school, you realise that it is just a smaller version of life, and really I have felt that I should have been an adult since I was aged about five.''
