Jack Osbourne has hit out at his mother SHARON for revealing his fling with Paris Hilton - and confesses it's not entirely true. The TV star refuses to reveal details of his tryst with the socialite, but he hints Sharon's description of a wild night of passion may not be completely accurate. He says, "My mum said that, not me, and there's not that much truth in it. I did have words with my mum. She likes exposing me."
