Morgan and Bode Miller announced the arrival of their identical twin boys on Tuesday.
The professional beach volleyball player shared photos of the twins, born on Friday, Nov. 8, and expressed her family's joy with the boys' arrival. She did not disclose the newborns' names.
"A day that couldn’t have been scripted and aligned more perfectly to bring these two into the world," Miller wrote in the caption of her post.
"Birth story is mind blowing and can’t wait to share," she added. "Insanely overwhelmed and grateful for all these gifts my baby girl keeps sending."
The announcement comes after the couple lost their 19-month-old daughter Emmy in a tragic drowning accident in June 2018 and welcomed a son, Easton, in October of the same year.
The couple have since become water safety activists, using their public platforms to spread more information about accidental drownings and pool safety.

"Losing a child while pregnant was the most confusing experience of my life. The conflict of emotions from what was pure joy turned to guilt and terror overnight. How could I love this baby the way I loved Emmy? Was it okay to love this baby the way I loved Emmy? It felt like by loving my son, I was trying to replace her. The fear of birthing my son and what that meant .....a monumental step forward....proof that time continued without her when all I wanted was for time to stop," she detailed in an Instagram post.
She shared that she soon learned the her son Easton "provided us an even closer bond to his sister."

"The moment I heard his cry, something sparked back alive in my soul," she explained. "Hope. Love. I’m not sure. But in that moment, I knew I was Mom and my kids deserved the world from me. Everything was going to be okay. My joy and grief could coexist."
She added that she had found "joy and excitement" to announce their family would be welcoming identical twin boys.
"From the day I met my husband, he has always said he wanted identical twin boys born on his birthday," she wrote. "We are due on the lucky day/angel number of 11/11 which is not far off from @millerbode Birthday of 10/12. From the beginning of this pregnancy, we knew Emmy had her hands in this miracle somehow."
