Thanks to Facebook, Jennifer Doering was able to find Gracie's mum, and reached out to get in touch.
The twins and their families came on to Good Morning America to meet each other for the first time and well... it was very emotional.
Just watch, and be sure to bring out the tissues.
The most heart melting moment was at the end, where Audrey said, "It felt like there was something missing, and now it's complete."
Wishing the girls and the families all the best!
