Sienna Miller and Kiera Knightley Upskirt And Laughing

'The Best Time of Our Lives': starring Sienna Miller and Kiera Knightley written by Kiera Knightley's mother Sharman Macdonald

Sienna Miller and Kiera Knightley co-starring in the upcoming movie 'The Best Time of Our Lives' have a real fun on the set. It's a pleasure to watch them! The movie is about menage a trois (i.e. love triangle) featuring a Welsh poet Dylan Thomas who loves two 'free-spirited' women (well, to be honest, judging from the pictures, 'free-spirited' is not enough to say). So the film promises to be an enjoyment to watch: two super sexy British celebs to engage in lezbian and heterosexual threesome with actor Matthew Rhys, who will play the hard-drinking poet. That Rhys is a lucky guy!

By the way, Kiera Knightley recently revealed she admires her co-star Sienna and even wants to be her as she cannot speak and behave in public like Sienna Miller does. Red carpet became a phobia for Kiera as she is afraid people will dislike her dress; all interviews the actress ends up "grinning aimlessly." Well, I hope Kiera Knightley did not mean what she said as she is one of my favourite celebs and I wish she did not turn into Sienna Miller.

So enjoy: Sienna Miller and Kiera Knightley on the set of 'The Best Time of Our Lives' (directed by John Maybury; written by Keira's mother Sharman Macdonald):
