Jude Law has cut short a family holiday in France because he's terrified on/off girlfriend Sienna Miller may stray, according to reports. The Alfie star has jetted to the Toronto, Canada set of her latest film Camille to keep an eye on the blonde actress after a string of media reports linking her with hunky co-star James Franco. Although Miller has furiously denied the rumours, a source tells British tabloid the Daily Mirror, "Jude is confused and Sienna wants to put that right. "She asked him to fly to Toronto so she can see him in person and he's told her he is prepared to listen to what she has to say. "She knows it might be embarrassing for him to bump into James but she wants to show him they are not having a relationship." The pair ended their engagement last summer (05) after Law admitted he'd cheated on his fiancee with his children's nanny, DAISY WRIGHT.
