Baby's first film festival!

Less than a week after announcing their pregnancy on Instagram, Jena Malone and her partner, artist Ethan DeLorenzo, hit up the 2016 Sundance Film Festival in Park City, Utah.

The former child star, who was on hand to promote her upcoming film "Lovesong," flaunted her burgeoning baby bump in a sleeveless LBD, which she wore with sheer black tights and knee-high boots, while making various promotional appearances on Jan. 24.

And despite the hectic schedule, Jena's musician-photographer beau was never far from her side.

Wonderwall.com spotted the couple packing on the PDA during a stop by the Variety Fandango Sundance Studio, where the "Hunger Games" actress made sure her baby daddy -- whom she affectionately referred to as "baby" -- loaded up on goodies from Dockers.

The 31-year-old actress made a joke about waddling up the stairs due to her size and could be seen rubbing her belly or resting her hands on her bump almost constantly.

The "Sucker Punch" star took to Instagram on Jan. 20 to announce that she was pregnant with her first child: "Womb to womb, to beating wing, I climb out of the eternal and into the shape of me," she captioned a photo of herself and her baby bump taken by Ethan. "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."

Continued the actress, "The shape your desires make out of you. The body you become to hold your dreams. 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"

We wish Jena and Ethan a healthy and happy pregnancy. From what we saw, they're in store for one!
