Jenna Johnson has revealed her baby boy's name.

On Tuesday, Johnson, 28, shared an adorable new photo of son Rome Valentin Chmerkovskiy, whom she shares with husband Val Chmerkovskiy, on Instagram.

The Dancing with the Stars couple previously posted glimpses of their baby, born on Jan. 10, but now Johnson shared a full-body photo of their bundle of joy in celebration of his 1-month birthday.

"Cannot believe it's been 4 weeks of being completely infatuated with you. Thank you for bursting my heart wide open and showing me what unconditional love is," Johnson captioned the sweet post.

While the couple kept the name under wraps, they had it picked out for years, Johnson told PEOPLE exclusively in July.

The couple selected names for their children long before the professional dancer was pregnant with their first baby.

Johnson has opened up about her journey toward motherhood, including the painful reality of experiencing months of negative results.

"I remember watching people share these videos and aching because I wished so badly I could experience that joy," Johnson wrote in a candid Instagram post shared last year. "After two years of infertility, and hundreds of negative tests after negative tests, it was heart-wrenching at times to stay optimistic and made me question whether I would ever have this opportunity."

She encouraged anyone struggling with pregnancy to not "lose hope."
