Emma Watson graduates from US university

Actress Emma Watson has graduated from a US university.

The Harry Potter star received her bachelor's degree in English literature from the prestigious Brown University in Rhode Island today.

She tweeted a photo of herself in a cap and gown as she prepared to join 2,000 fellow students collecting their qualifications at the Ivy League institution.

The 24-year-old started at Brown in 2009 after saying she hoped the broad curriculum offered by US universities would help make up for lessons she missed while making the Potter films.
