"I mean, we're quite nerdy. We talk about books and we play cards and do The Guardian crossword. We were living together in this house in Wales that was really beautiful and we all sort of walked around in our pajamas and went for long walks. Oh god, she's going to kill me now. She's not a nerd. I can be. No one will believe it anyway."

Wouldn't bet on that, Sienna. Is there no end to the wanton debaucheries in which this pair indulge themselves? Even after filming they remain in touch and carry out their sinful and wicked deeds.

"We swap books. I went to her house for dinner the other day and she's given me books and she's learning the flute at the moment, I'm learning the piano, quite nerdy."

That's quite enough of this outrageous pair. Let's hope they don't team up with 'Mad' Kate Winslet and form a little chamber orchestra.
