Wow! Scarlett Johansson stuns in skintight mini dress

It's hard to believe that Scarlett Johansson gave birth to her daughter Rose just four months ago.

The new mother, 30, hit the arrivals line for the G'Day USA Gala and AACTA International Awards at the Hollywood Palladium looking fabulous in a stunning mini dress.

As E! reports, she attended the event to present Chris Hemsworth, her Avengers co-star, with this year's Excellence in Film Award -- a presentation in which she called the actor "shockingly handsome."
