Actress Scarlett Johansson has delivered in spades since Mango hired her to rep for their fashion line three years ago. Her star keeps getting brighter in Hollywood. And, she couldn’t look hotter in new photos.

Johansson last star turn was in “Iron Man 2,” where she virtually stole the movie as Natasha Romanoff, aka Black Widow.

She played against some actors with pretty solid cred, like Robert Downey Jr., Mickey Rourke and Gwyneth Paltrow.

She’s next set to star again with Downey and Chris Evans in “The Avengers,” based on the Marvel comic book and slated for release in 2012.

More immediately, she’ll be hosting NBC’s “Saturday Night Live” when the show returns Nov. 13 with musical guest Arcade Fire. It will be her third appearance.

Johannson’s sultry looks have been tapped for advertising campaigns by Calvin Klein, L’Oréal and Louis Vuitton.

Domenico Dolce and Stefano Gabbana invited her to join them at the Metropolitan Museum of Art’s Costume Institute Gala last year, and were so smitten by her. they made her the face of the new Dolce & Gabbana make-up collection in early 2009.

Scarlett also presented at the Mango Fashion Awards held at the National Art Museum of Catalonia last Wednesday (Oct. 20) in Barcelona, Spain.

This is the third time the actress has launched the firm’s new designs.

The photo shoot took place in a London mansion, and photographer Mario Sorrenti was behind the lens.

Jane How was responsible for the styling, while Lucía Pieroni handled make-up and and Oribe hair styling.
