Harry Potter star Emma Watson has officially graduated from Brown University in Rhode Island with a degree in English literature.

The British actress donned the traditional cap and gown to pick up her diploma on Sunday (25May14).

The 24 year old then posted a graduation day 'selfie' on Twitter.com.

Watson spent five years studying for her diploma - she took a break in 2011 to promote the final Harry Potter movie, The Deathly Hallows: Part 2.
