Scarlett Johansson looked gorgeous for the photocall announcing her official involvement with Mango. The wife of deliciously hot Ryan Reynolds has nabbed the fashion line’s Autum/Winter 2009 campaign.

Scarlett hosted a party at the Santo Mauro Hotel in Madrid, Spain in which the actress follows in the footsteps as her Vicky Cristina Barcelona co-star Penelope Cruz as the face of the brand. Cruz had been the front woman for Mango for 4 seasons, but handed over the reigns to Johansson.

The blonde bombshell went auburn with red hues for the event. I can’t quite decide which color suits her best. I am leaning toward the blonde, but brunettes are running the show in trends at the moment. What do you think?
