One very sweet red carpet moment!

Four days after announcing her pregnancy, Jena Malone worked her baby bump on the red carpet for the first time at the premiere of Lovesong at the Sundance Film Festival on Monday, January 25, in Park City, Utah.

The Hunger Games alum, 31, hit the step and repeat in a sleeveless, black and white Sea dress with a plaid bodice. Malone, who's expecting her first child with musician and photographer Ethan DeLorenzo, also donned a matching coat by the label. Candy apple-red ankle booties (and a perfectly matched lip!) completed the ensemble.

While the dress camouflaged the actress' shape then, there was no hiding her bump the day before! Malone posed for photos with her Lovesong costar Riley Keough while wearing a little black dress, which highlighted her shape — especially when Keough put a hand on her belly.

On January 20, the Sucker Punch actress revealed that she was pregnant via Instagram with a bump-cradling photo and a poem. "Womb to womb/To beating wing/I climbed out of the eternal/And into the shape of me," Malone began. "Some words I wrote years ago when I was thinking about my own mother. And the woman she was when she had me. And the woman I was reaching to become. The shape your desires make out of you. The body you become to hold your dreams."

She continued, "It's with two feet firmly on the ground and a heart swelling in an ocean of love that I'd like to share the new shape I am becoming to hold the greatest dream of them all. #babybump #newparents #impossibleproject Polaroid taken by my beautiful hearted baby daddy @uglyhippie."
