Malone followed up DeLorenzo's post with her own Instagram photo, also taken by DeLorenzo, and also featuring her showing off her adorable bump. The actress included a poem in the caption that she says she wrote several years ago about her own mother, and "the woman I was reaching to become" as a mother herself.

"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," Malone added.

Congrats to the happy couple!
