A “spy” spied Jude Law and Sienna Miller hanging out on Thursday night after their respective Broadway performances. Jude stars in Hamlet and Sienna stars in After Miss Julie. The two hit up The Box at 1 a.m. where they got a table with a few friends, got drunk, laughed, possibly whispered sweet nothings in each others ear and left together at 3:30 a.m. Naturally, we’ll jump to the conclusion that they’re hooking up again.

“Jude’s a regular at The Box and a lot of people know him there,” the source said. “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.”

So much so, in fact, that at one point he brought the actress to meet another group of friends, and led her through the crowded club by the hand.

“It looked like he wanted people to see that they were together,” the partygoer dished.

I’d hate to be Jude and have all these people swarming around me when I’m trying to get some chick drunk. That must be annoying. Having witnesses.
