There's no doubt that Malone is one of Hollywood's crunchiest parents. The actress announced her pregnancy through a poem in January, writing:

"Womb to womb
To beating wing
I climbed out of the eternal
And into the shape of me."

She and partner DeLorenzo also took a "baby mooning" trip to Yosemite together in April.

Baby mooning in Yosemite and the western sierras. Sleeping under the stars and building fires amongst the sequoias. Getting giant and getting my head wet in the coldest alpine springs. And powerful mists from the most spellbinding waterfalls. Growing a human. With the simplest of ingredients How soon we forget How truly little we need To live Photo by my everything @e.delorenzo
