Scarlett Johansson flaunted her post-baby body just four months after giving birth to her daughter Rose Dorothy. Her body looked slim and toned when attending the G'Day USA Gala and AACTA International Awards at the Hollywood Palladium on Saturday, January 31.

Scarlett wore a tight halterneck mini dress with white and red stripes and matching fringe embellishments. Styling her short blonde hair in voluminous updo, the "Captain America: The Winter Soldier" actress completed her look with a pair of black heels and some accessories.

Scarlett attended the event to present her "Avengers: Age of Ultron" co-star Chris Hemsworth with the Excellence in Film Award. Chris was joined by his wife Elsa Pataky and his brother Liam Hemsworth.

When presenting the award, Scarlett recalled being in a plane with Chris and other "Avengers" co-stars Mark Ruffalo and Chris Evans during a press tour. "Chris decided to take a little cat nap," she said of the "Thor" actor. "He collapsed into a giant perfect heap, his lion's mane gracefully falling around his prominent chiseled features. 'My, God,' proclaimed Ruffalo, 'what a specimen.' Evans added, 'It's incredible-the man is perfect even when he's drooling.' "

The "Lucy" actress said she "just stared hoping that some of his stardust would drift my way," before adding, "He's all at once sensitive and ferocious, otherworldly and grounded, is shockingly handsome and is surprisingly approachable. He is every man and like no man you've met before. He is versatile despite his physicality, which makes him a grade A movie star."
