Scarlett Johansson let her hair down on the 2011 Academy Award red carpet, like, literally! Rather than a typical updo, she chose to wear her locks free and loose.
The sultry actress wore a daring backless dress with a sexy lace front and floral accents. She posed on the red carpet with fellow actor Jeremy Renner, and the two will also be paired in the upcoming movie The Avengers. They seem to be quite cozy off the set!
