Emma Watson at Oxford Uni

Emma Watson - who played Hermione in Harry Potter - has started at Oxford University.

The star has announced she's taking a break from making movies in order to concentrate on her studies.

Emma wrote: "To Everyone who is starting a New School Year, (sorry those who have been at school for a while Oxford starts late). Just to say have a great term and good luck with all your work.

"You might not hear from me for a while because I will be really busy studying but I wanted to just say hi and bye."

Next summer she'll return to Brown University in the US to finish her degree.
