The girls began video chatting, which allowed them to communicate with each other for a few weeks, but they didn't meet in person until this week.
They reunited for the first time in person on "Good Morning America."
The two girls burst into tears and hugged each other.
"It's very overwhelming," said Gracie.
"It felt like there was somebody missing," said Audrey. "Now, it's complete."
