Last week we should’ve seen the first premiere of “Iron Man 2″ in London, but it was canceled due to the ash clouds.

Instead the stars of the movie gathered for a photocall at the Four Seasons hotel in LA on Friday afternoon.

Scarlett Johansson – who wasn’t in the first movie – looked beautiful wearing a dove grey RM by Roland Mouret Artemis dress.

The short sleeved dress has all of Mouret trademarks – a strong silhouette, panelled high waist and a zipper that runs down the back of the dress.

I love the dress, but I wish ScarJo’s Christian Louboutin heels had been a bit more exciting.

Her make-up is flawless and I’m loving the big bouncy wavys.
