Reunions are always emotional to watch, but this special moment between twins will really touch you. Audrey and Gracie are 10-year-olds who were adopted from China and raised in the USA. Not knowing that the other even existed, one was raised in Washington State while the other grew up in Wisconsin. When one of their mothers started researching her family history, however, they discovered that it was not just one girl from China, but twins. Good Morning America arranged for both families to come for the reunion, and there were tears all around.
