"On the road again," she shared. "Pregnancy after loss is a whole other thing. After two miscarriages in a row, we were ready to call it. I stopped trusting my body and started to accept the fact that I was done. As a birth attendant, I’ve seen and heard it all. It takes everything I’ve got to detach lovingly from the losses I’ve been present for and be in my own experience."

Kirke is also the mother to Cassius Riley from her previous relationship with musician Morgan O'Kane.

"When I was pregnant at 25, I knew nothing," she continued. "I had no community. I dove in blissfully unaware about birth and its mysteries. Now, with 10 years worth of experience to pull from, I treasure my birth community and the knowledge I have. You’re already teaching us how to stay in the day in a way we’ve never had to, little one. Thank you."

According to Us Weekly, Kirke and the Gossip Girl alum began dating in 2014 and married in 2017.

Congrats to Domino Kirke and Penn Badgley!
