The pair revealed their baby news in January, sharing a carousel of sweet family photos featuring Josie wearing a pink t-shirt that reads "big sister."

On the Netflix reality show, Ballatori and Kissinger were tasked with deciding whether to break up or get engaged after living with six other couples facing the same dilemma on the 10-episode series. The couple ultimately opted for the latter and even tied the knot at the end of the finale.

Ballatori announced that she and Kissinger were expecting their first baby together on Instagram in early April 2022.

"Here's to my husband- thank you for the most incredible year of my life. Being married to you and starting our family has been the greatest gift," Ballatori wrote on Instagram. "I am beyond blessed to have such a passionate, loving, strong partner to share this life with. We are so lucky to be loved by you. - your girls💕 3 MORE WEEKS UNTIL OUR BABY GIRL ARRIVES!"

Ballatori and Kissinger welcomed their first baby together, daughter Josephine "Josie" Riley, in May 2022.

"We could not be more in love. God is so good," Ballatori wrote on Instagram alongside a video of her cuddling with her newborn daughter. "Big thanks to the incredible team of doctors and nurses who helped us throughout our stay. We are so thankful to be home together as a family now."
