Sienna Miller and James FrancoSienna Miller’s publicist might insist there is nothing going on between her client and Camille co-star James Franco but that’s not convinced Jude Law.

Sienna and James have been spotted looking “very into each other” on their days off from filming in Canada and apparently it’s worried Jude.

A source told the Mirror: “Jude is confused and Sienna wants to put that right. She calls James ‘the Matinee Idol’ because of his good looks, but insists that nothing is going on - yet Jude thinks there’s no smoke without fire.”

“Sienna 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.

“He wants to believe it but they both have trust issues from the past.”

Sienna and Jude called off their engagement last year after it was revealed that Jude was having an affair with his children’s nanny, Daisy Wright. They got back together in May this year to “work things out”.
