'You' Star Penn Badgley Welcomes First Child With Domino Kirke

And taking to Instagram on Sunday evening, Domino revealed she had given birth to the baby boy back in August. We're so pleased for these two!

Posting on social media, Domino wrote: "His heart shaped home #40dayspostpartum#placentaart," along with an image of the placenta printed on paper.

Domino also added an adorable image to her Instagram Stories, of Gossip Girl star Penn, their new arrival and their pooch sleeping on the bed. So cute.

Sadly, when Domino - a singer and doula - announced her pregnancy back in February, she revealed the couple had suffered two miscarriages in a row.

"On the road again... pregnancy after loss is a whole other thing," she wrote.

"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.

"When I was pregnant at 25, I knew nothing. 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."

Penn, 33 and Domino, 36, started dating back in 2014 before getting married in February 2017. Domino is also mum to son Cassius Riley, born in 2009.

Congrats to the whole family!
