Sienna Miller Ready to Boot; Rhys Ifans Ready to Hit That

This is not a Sienna Miller nude photo.

But it actually may be more fun to look at.

Take a look at Miller, coming back from yet another night of partying, ready to blow. And we don't mean her new man, Rhys Ifans, sitting up front. Although that will probably come later.

For now, we're just talking some serious chunks.
