Scarlett Johansson shows off stunning figure and ample assets at Captain America premiere

SCARLETT Johansson looked every inch the sexy siren earlier tonight as she slipped into her best dress and headed to London's Westfield for the premiere of Captain America: The Winter Soldier.

The star, who has slipped back into a slinky catsuit to reprise her role as Natasha Romanoff in the latest Marvel caper, looked stunning as she arrived on the blue carpet, showing off her stunning figure and ample assets.

Opting for a figure-hugging ensemble, the 29-year-old posed up a storm as she joined her co-stars, including Samuel L Jackson, for the UK premiere.

The deep red frock featured a hemline that stopped just above her knee, showing off her shapely legs, as well as a revealing neckline that made the most of her ample cleavage.

And ensuring her chest was not short of attention, the newly-engaged actress accessorised with a stunning diamond necklace.

She teamed her look with a pair of leopard-print shoes and a deep red lipstick, giving her an air of hollywood glamour, while wearing her hair in an exaggerated side-parting.

Scarlett kept the rest of her accessories minimal - simply showing off her huge sparkler, given to her by fiancé Romain Dauriac.

The star appeared in great spirits as she happily posed for pictures with fans, who had waited for hours to catch a glimpse of the A-listers.

Earlier in the day, Scarlett opened up about her action movie roles revealing that she will be "forever wounded" after nursing ongoing injuries.

Speaking about her bumps and bruises at a press conference held this afternoon, the actress said: "I am forever wounded from these movies. I have old injuries from Iron Man 2 and I keep re-injuring them. That's part of the joy and part of the process, I guess."

However, she added that despite the risks, she prefers to do as much of her own stunt work as possible.
