Jude Law and Robert Downey Jr. share a private joke (and maybe a little pee) at the Madrid, Spain premiere of Sherlock Holmes. Something tells me these two were quite the little mischievous guys on the set.

There is definitely lots of chemistry with this cast both on and off the set, and no I’m not talking sexual chemistry which I completely understand why you would draw that conclusion with me, natch.

Maybe Jude is laughing at the rumours that he is set to propose to Sienna Miller?
