Jude Law and Daisy Wright

Super-star actor sleeps with the nanny: it seems like the worst cliché in the world, but that's exactly what Jude Law did when he was engaged to Sienna Miller in 2005. Naughty boy. But at least, unlike so many other stars with a wandering, ahem, eye, he actually admitted it. Law claimed he was 'deeply ashamed' and 'sincerely regretted' hurting Sienna - but the apology wasn't enough and the relationship ended. The couple rekindled their romance years later and are rumoured to be getting married next year.
