Emma Watson clutched a graduation-themed teddy bear as she arrived at Heathrow Airport in London last night. She just returned to the UK from the East Coast, where she's been busy filming The Perks of Being a Wallflower. Emma's about to switch gears to do press for Harry Potter and the Deathly Hallows Part 2, which she's already started promoting with multiple magazine covers. Emma Watson is on the cover of July's Vogue, and she also posed for a spread in Seventeen. Deathly Hallows is the final installment in the Harry Potter franchise, and Buzz has a sneak peek at pictures from Harry Potter and the Deathly Hallows Part 2 ahead of its July 15 release date. Harry and his crew may finally be retiring, but author J.K. Rowling is still working on the series and recently created a new website called Pottermore that will allow fans to interactively read the Potter books and enjoy other content when it officially launches later this year.
