Congratulations are in order for Jena Malone! The Hunger Games actress, 31, welcomed her first child with boyfriend Ethan DeLorenzo—baby boy Ode Mountain DeLorenzo Malone—and announced the news on Instagram Tuesday. "The best weekend of our lives!!! What an incredible blessing to be chosen by this amazing, kind, gentle and beautiful soul to be his parents," she wrote alongside a black-and-white photo of them cuddling their bundle of joy as he yawned in their arms. "Humbled and in complete awe that we get to experience the most ancient and transcendent love that exists. Thank you Ode Mountain DeLorenzo Malone."

In celebration of their son's arrival, Ethan also shared a sweet black and white video of him and Jena cuddling their newborn and smiling at him.

The new mom, who has posted artistic photos of her bump on the 'gram throughout her pregnancy, first announced that she was expecting in January. After showing off her burgeoning belly in a Polaroid, she captioned it, "Womb to womb To beating wing I climbed out of the eternal And into the shape of me"

She went on to explain the caption, writing, "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. 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 @e.delorenzo"

Congrats to the couple!
