The inquiry into the 'News of the World' phone-hacking scandal gets more star-studded with the news that 'Harry Potter' author J.K. Rowling, Sienna Miller and Hugh Grant are expected to be among those giving evidence at an inquiry ordered by British Prime Minister David Cameron.

They're been named "core participants" along with 43 other celebrities, athletes and other public figures who believe they have been the victims of media intrusion. They can give evidence in person or via their lawyer at the inquiry, which begins in October at London's Royal Courts of Justice.

Grant, of course, once played a very groovy (and fictitious) PM in the film 'Love Actually,' where the biggest scandal he had to deal with was fancying the girl who brought him his tea and being caught boogieing to The Pointer Sisters' 'Jump.'

Rowling and Miller has both been popular paparazzi targets: In 2008, Rowling won a legal battle with the press after photographs were published in the Sunday Express of her son.
