At the screening of her upcoming film, Scarlett Johansson almost had a wardrobe malfunction

The sight of a star flashing the flesh on the red carpet is hardly unusual but it all seemed to go a bit wrong for Scarlett Johansson at the Captain America screening in London on Friday.

The actress rocked the premiere in a red dress which left plenty of leg on show.

However, it wasn't her pins we were drawn to - the star's boobs seemed to have a life of their own and were hoisted up extra high in her frock from Vivienne Westwood's Red Label collection.
