Exciting news for Jena Malone! The Hunger Games actress took to Instagram on Tuesday to announce her engagement to boyfriend, musician Ethan DeLorenzo.

To add another layer of cuteness to the story, the 31-year-old enlisted the help of their three-month-old son, Ode Mountain, to spread the word. Malone shared a sweet photo (below) of little Ode with her hand resting on his head. And although slightly out of focus, a giant, glittering rock is visible on her ring finger.

"One day, after all the youthful rushing quiets in your heart, you realize there's nothing more you need. Nothing more you want to achieve than to build your life around love. And oh the things we will get to build together," she captioned the snap. "I couldn't be happier. I love you Ethan. #isaidyes"

Instagram announcements are nothing new for the former child star. Back in January, Malone announced that she and DeLorenzo were expecting their first child via the photo sharing app. "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." she wrote alongside a photo of her burgeoning baby bump in the shadow of a mountain.

Congratulations to the happy couple!
