British model/actress Sienna Miller has fuelled speculation her relationship with Jude Law is over for good after being snapped cavorting with her latest co-star. Miller and James Franco were photographed getting close on location in Canada while shooting new movie Camille. A source tells British tabloid the Sunday Mirror, "They have a strong chemistry. He is bowled over by Sienna. "It's as if she's trying to make Jude angry." Miller, 24, and Law ended their seven-month engagement in July 2005 after the Road To Perdition hunk admitted he had slept with his children's former nanny DAISY WRIGHT the previous March (05). They have since made numerous attempts to rekindle their relationship.
