Sienna Miller hooks up with James Franco

Looks like Jude Law and Sienna Miller are playing things casually on this, their millionth reconciliation. The on-again, off-again couple must have decided monogamy is not for them as Sienna has been spotted getting mighty close to her Camille co-star, James Franco. Then again, perhaps Sienna has been locking lips with James off-screen merely for the benefit of her character.

Canada.com claims Miller and Franco started “dating instantly� after meeting in Canada to film Camille. Over the weekend the new lovers were seen at a Wilco concert and at a showing of the new Pirates of the Caribbean film. Canada.com reports that Sienna and James also did some shopping, eating and clubbing together. Sounds like a busy weekend. Spies for the popular gossip allegedly saw James “tenderly caressing [Sienna’s] face and stroking his fingers through her hair.�

While Sienna has had more than a few famous hook-ups (Jude, Daniel Craig and Hayden Christensen, for example), James has far fewer celebrity notches on his bedpost. He did, however, date Marla Sokoloff, his co-star in Whatever It Takes. Interestingly enough, Franco shares his birthday with one of Miller’s other conquests, Hayden Christensen, though he is three years older than the Star Wars actor.
