Baby boy for Jena Malone

Jena Malone and Ethan DeLorenzo have welcomed their first child together.

The 'Hunger Games' actress took to Instagram to reveal that she gave birth to son Ode Mountain DeLorenzo Malone over the weekend.

She wrote: "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.

"Humbled and in complete awe that we get to experience the most ancient and transcendent love that exists.

"Thank you Ode Mountain DeLorenzo Malone (sic)."

Jenna, 31, and musician, producer and photographer Ethan, who was a member of Chris Brown's band from 2010 until 2012, announced her pregnancy in January with a post on the picture-sharing website.

She wrote: "Womb to womb To beating wing I climbed out of the eternal And into the shape of me 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 (sic)."
