Scarlett Johansson always brings a heavy dose of sexy to the red carpet, and last night at the premiere of The Avengers was no exception! The blond bombshell took a cue from her character in the movie, Black Widow, and selected a body-hugging, black Versace number that showed off her amazing curves. She complemented her look with strappy black heels from Giuseppe Zanotti, jewels from Van Cleef and Arpels, and a retro updo. Watch today's Fab Flash to see her gorgeous look from head to toe. On Allison McNamara: Smythe blazer, Urban Outfitters top.
