In what seems to be very Pam Anderson/Tommy Lee, Jude Law and Sienna Miller recently appeared to be “more than just friends” during a night out.

The former couple, who split up in November 2006 after the Sherlock Holmes star had an affair with his children’s nanny, fueled speculation they have rekindled their romance during a visit to New York nightspot The Box last Thursday, where their intimate behavior attracted attention.

One onlooker said, “They came in together and got a table with a few friends around 1am. At one point, Jude ordered shots for the two of them, and he was egging her on to take one. They were laughing a lot and whispering to each other - it looked like they were genuinely having a good time. They certainly looked like more than just friends.”

During the evening, Jude - who is currently starring in a Broadway production of Hamlet - was approached by several women but was quick to turn down their advances.

The source added, “Jude’s a regular at The Box and a lot of people know him there, so he had a ton of people coming up to say hi to him, many of them female, but he really only seemed interested in Sienna. It looked like he wanted people to see that they were together.”

Sienna, who is starring in Broadway production of After Miss Julie, recently quashed speculation she and Jude had got back together, admitting they had met up while both working in the US but insisted they are just friends.
