Side Boob

What exactly is Sienna Miller trying to promote? The insatiable man-stealer stars in the upcoming (rumored) crap fest G.I. Joe: Rise of the Cobra and, while she's not shirking her promotional duties, she sure has an interesting take on getting press. She already entered a wet t-shirt contest of one when she showed up at a recent G.I. Joe screening event via a speed boat - and happened to be wearing a thin white shirt. Up next? Going braless and flashing "side boob" on Regis & Kelly, naturally. Leave it to Sienna to make daytime television R-rated. Click here for the video of Miller sluttin' it up.
