Sienna, Sienna, Sienna – SIT YOUR ASS DOWN! You are doing WAY too much. Although no photos were captured of the moment, sources say that Lindsay Lohan’s ex-hook up buddy, Model Jamie (James) Burke, was locking lips seriously and publicly with none other than MS. ULTRA TWAT herself – Sienna Miller! Burke also used to rendezvous with Kate Moss and we KNOW how she likes to get down. Sienna and Jamie were caught smooching it up at Gramercy Park Hotel in NY. Sienna gets around…literally! She’s jet-setting, coast-jumping, and country-changing. But in addition…Jude dumped it, Jamie’s hitting it, Diddy’s using it, and Hayden is sharing it with the entire world via “Factory Girl”. We here at Coup d’états will start calling this girl:

See-in-her Miller instead of Sienna from now on – because her goodies need a REST!

Eww! Hollywood is turning into one big never-ending game of six degrees of separation! The grand prize is going to end up being the gift that keeps on giving – a nice case of herpes – if some of these celeb crazies don’t have a seat.
