J.K. Rowling and Emma Watson are due to attend the 2009 Raisa Gorbachev Foundation ball this weekend. The Russian-themed event will take place at Stud House, Hampton Court in London. Proceeds from the night will be split between the cancer foundation and Marie Curie care, with tables coming in at a cost of £15,000 each. There will also be an auction.

J.K. Rowling, Emma Watson and Ralph Fiennes (Voldemort) also attended the 2007 event, pictures from which can be seen here.

We will have photos from the ball as soon as they are available.
