The Blossom in the Dust star and her music executive husband Ryan Dokke welcomed daughter Scarlett Ruth Dokke in January, 2015, and a little over a year later, Mallary has revealed she is expecting again.

The mum-to-be took to Instagram to post a picture of herself cradling her growing baby bump while standing next to Ryan, who is holding little Scarlett wearing a shirt which reads: "I'm getting promoted to big sister".

Mallary added the caption, "When you find out you’re going to have to start sharing Mom & Dad soon..."

The singer, who is due in November (16), later shared a photo of her sonogram photo and gave hope to other women who have suffered through miscarriages and tough pregnancies, like she has.

"So many people go through this and I just wanted to share our story," she wrote. "I've never been one to shy away from my honesty or share what’s on my heart.

"I’ve written a song about it and hope that I am able to sing it without crying soon. I wrote it to give a voice to those babies that never make it & I have hope.. Beautiful hope that someday when I see Jesus he will be holding those tiny little babies and allowing me to show them how much I wanted them."
