LOS ANGELES, Aug. 31 (UPI) -- Jena Malone and boyfriend Ethan DeLorenzo are engaged.
The 31-year-old actress announced the news in an Instagram post Tuesday, three months after giving birth to their son, Ode Mountain.
"One day, after all the youthful rushing quiets in your heart, you realize there's nothing more you need," Malone captioned a close-up photo of her son.
"Nothing more you want to achieve than to build your life around love," she added. "And oh the things we will get to build together. I couldn't be happier. I love you Ethan. #isaidyes."
Malone and DeLorenzo, a singer and photographer, welcomed Ode in May following a babymoon trip to Yosemite National Park. The actress gushed about DeLorenzo in a post the next month, calling him "the living, breathing definition of a true partner."
"Your sacrifice and dedication to the ones you love. Your patience and humor. Your warm heart," she wrote. "You're 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."
Malone is known for playing Johanna Mason in The Hunger Games film series and has since appeared in The Neon Demon. She will next star in Bottom of the World with Vinyl actor Douglas Smith.
