Steve Granitz/WireImageMotherhood definitely looks good on Scarlett Johansson.
The actress, 30, who gave birth to daughter Rose four months ago, showed off her post-baby body last night at the G'Day USA Gala and AACTA International Awards at the Hollywood Palladium.
The Lucy star slipped into a short tight red, white and black Preen halter with fringe that fell about halfway down her thighs.
ScarJo, who attended the event to present her Avengers co-star Chris Hemsworth with this year's Excellence in Film Aware, wore little jewelry and rocked killer Brian Atwood heels and her blond-highlighted faux-hawk.
During the show, she sat next to Hemsworth and chatted and laughed with the Aussie actor and his wife Elsa Pataky.
E! News exclusively reported in March that Johansson was expecting her first child with her then- fiancé Romain Dauriac.
Her rep announced they had welcomed a baby girl, whom they named Rose, in early September. "Mother and daughter are doing well," the rep said in a statement.
The actress and the French former journalist married about a month later in a secret ceremony in Montana.
Johansson will next be seen in Avengers: Age Of Ultron and most recently shot Hail, Caesar!, a Joel and Ethan Coen film starring George Clooney, Josh Brolin, Tilda Swinton and Ralph Fiennes.
