Sitting next to her in a lecture, a hungover student might be mistaken for not recognising Emma Watson.
Dressed down in jeans, boots and an anorak, the Harry Potter actress looked like any other proud newbie on her first day at Oxford University.
Only Watson is worth £24million and is a global superstar.
The 21-year-old beauty posted a picture of herself on her blog, grinning at the camera with her thumb up as she posed outside the iconic building.
Watson also clutched an armful of books and revealed she will be 'busy studying' as she embarks on the new term.
The Burberry model 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.'
The young star put her education on hold at America's Brown University earlier this year to focus on her acting.
She has since made My Week With Marilyn, due out later this year, and The Perks Of Being A Wallflower.
But Emma has said she will return to Brown to complete her degree.
She remains enrolled at Brown, even though she will study at Oxford this autumn, and intends to return to Providence, Rhode Island, next year to complete her studies at the Ivy League school.
