Sienna Miller is popular for many things, but her pussy control is not one of them. Good for her, we really love celebrities that like to "do it".

That said, here come the news: Sienna Miller was just caught making out with Cillian Murphy at the Groucho Club in London.

During the filming of the movie Hippie Hippie Shake, where both European actors worked together, sparks flew between the two and the result appears to be a steaming romance that is probably making Balthazar Getty regret the hell out of having breaking up with Sienna.
