Jena Malone is engaged to Ethan DeLorenzo!

The actress debuted her diamond engagement ring on Instagram Tuesday along with an adorable photo of the couple’s son Ode Mountain.

“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. I couldn’t be happier. I love you Ethan,” she captioned the portrait along with the hashtag “#isaidyes” and a diamond ring emoji.

Malone, 31, and her photographer beau welcomed their 3-month-old son in late May, after announcing the pregnancy in January.

Before giving birth to Ode Mountain, the Hunger Games actress gushed about DeLorenzo on social media.

“Thank you for being the living, breathing definition of a true partner. Your sacrifice and dedication to the ones you love. Your patience and humor. Your warm heart,” Malone captioned a photo of her man. “Your (sic) the best man I’ve ever met and I can’t wait to watch you become what you were destined to become, an amazing father.”
