Earlier this month, Viall and Joy announced that they’re expecting their first child.

“Our biggest dream came true,” the couple wrote Aug. 8 on Instagram.

"We have both always been excited about becoming parents someday, and we are so excited to be on this journey together," he added.

Viall and Joy got engaged in January when the Viall Files podcast host popped the question with a Brilliant Earth 18K yellow gold ring set with a 5-carat elongated cushion cut diamond. The pair celebrated three years together in July.

“I love our family we’ve started together can’t wait to see how it grows,” he wrote on Instagram on July 11. “Thanks for 3 incredible years and for always fighting for us. Can’t wait for the rest of our lives together.”

For their anniversary, Joy declared on Instagram that she “couldn’t have dreamt up a better man” than Viall.

“Thank you for loving every piece of me,” she wrote. “You make me feel heard, seen, valued, cherished, beautiful, safe, confident, protected, challenged, nurtured i could go on and on. but most importantly you grew flowers in the darkest parts of me (said perfectly by the one and only Zach Bryan) i didn’t think it was possible to find someone who could stand beside me, and give me every ounce of encouragement and love as i put back together the most broken parts of myself. i finally feel whole.”

Joy also thanked Viall “for being the man you are,” and added, “i can’t wait to marry you!!!!”
