Hilton's pal comes clean about Ray J sex tape

Paris Hilton's best pal Kim Kardashian has confirmed she and ex-boyfriend Ray J filmed a sex session - and now she's trying to make sure it doesn't go public.

The tape featuring the socialite with Brandy's little brother, who is now dating Whitney Houston, has allegedly found its way into the hands of bosses of Internet and DVD porn giants Vivid Entertainment, who hope to post the footage in cyberspace.
