Actor Jude Law won't be thrilled with his latest 'award' - his tryst with his children's nanny DAISY WRIGHT while he was dating Sienna Miller has been named Hollywood's sneakiest affair. The Cold Mountain actor's affair topped the US magazine poll - and he was closely followed by Billy Crudup who came second for leaving his pregnant girlfriend Mary-Louise Parker for fellow actress Claire Danes. Keith Urban, Sean 'Diddy' Combs, and Meg Ryan all received the dubious honour of making the top 10.
