Harry Potter author JK Rowling has comics Peter Kay and David Walliams under her spell at a charity bash. The 43-year-old writer, in a plunging sky blue gown, cuddled up to the pair at the Raisa Gorbachev Foundation Annual Fundraising Gala Dinner. Host was ex-Soviet leader Mikhail Gorbachev who set up the cancer charity in memory of his late wife. Others at the South West London party were Jamie Cullum, Sophie Dahl and PM's wife Sarah Brown.
