Emma Watson posed with a mannequin of her character Hermione over the weekend when she visited the Warner Bros. Studio Tour - The Making Of Harry Potter.
"Still got it. #HarryPotterWorld #Watford" wrote the Bling Ring actress alongside the picture which she uploaded to her Twitter page.
The 23-year-old actress was among several other former Harry Potter stars that attended a fundraiser at the studios for author JK Rowling's Lumos charity.
Raising over £1million for her charity, which gives money to disadvantaged children, Joanne said: "Since setting up the charity eight years ago to help change the lives of so many children living unnecessarily in appalling institutions across the world, Lumos has already helped governments to take nearly 12,000 children out of these institutions."
