Sienna Miller smoking yellow shoes gray pants black shirtyellow shoes no bra

So that's her trick to snagging all those hot married men!

We snapped the homewrecking hottie leaving the gym yesterday afternoon, and these awkward trousers and yellow oxfords definitely aren't her best look. Then again, seeing as she worked up a sweat and then lit up a cancer stick immediately afterwards, we're guessing she wasn't smelling too good either!
