Rosie Huntington joined the equally hot and sexy Josh Duhamel (in Simon Spurr) during the press conference for “Transformers: Dark Of The Moon” earlier today in Rio, Brazil at the Copacabana Palace.

Against the glorious blue sky backdrop Rosie looks radiant wearing head-to-toe Michael Kors.

Her black chiffon jersey racer-back Michael Kors Fall 2011 dress, was paired with a black leather asymmetric belt from the same collection.

I love the lightness of this black look via the floaty chiffon skirt. Black can tend to seem so heavy in summer, but not on this occasion.

Sleek long tresses and Michael Kors black leather ankle cuff heels we saw in the last Rosie post completed the look.

I have a feeling this is going to be an amazing promo tour for Rosie.
