Just when we thought Emma Watson finally shook her "Harry Potter" character Hermoine Granger, "The Bling Ring" actress and author, JK Rowling returned to the world of witchcraft and wizardry for a charity event.

According to Entertainment Wise, the event, held for the charity Lumos featured the reunion of several cast members including Alan Rickman who played Professor Snape.

The fundraiser took place at the Warner Bros. Studio Tour London - The Making of Harry Potter near Watford.

The GQ cover girl tweeted a photo of herself next to a fake body double, with the caption: "Still got it. #HarryptterWorld #watford".

Reliving old memories Emma Watson took to her Twitter account to post a photo of herself next to a fake body double of her fictional character with the caption, "Still got it. #HarryPotterWorld #watford."

As far as the charity goes JK Rowling was told the Sunday Mirror, "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.

"We have prevented the deaths of more than 400 extremely vulnerable children with disabilities, who were not receiving the care they needed in institutions.

"We have helped the EU change its rules on how it uses money to reform health, education and social services - and we are just beginning."

She went on to say, "There is so much more we need to do to bring an end to the institutionalization of children. The incredible support we have received tonight will directly go towards helping achieve all this."

The author was able to raise money by auctioning off items that were bid on by celebrities including the likes of John Bishop, Richard Curtis, Stella McCartney and Hugh Grant.
