If you are referring to Bebe from Myanmar, them the correct answer is that she is a Karen. The Karen are a minority group from Burma/Myanmar which is located North of Thailand. The Karen were an ethnic minority that was constantly attacked by the local Burmese soldiers in the history of their conflict.
Her childhood was not the happiest one. She was born in a United Nations camp for refugees which was located in Thailand, called Mae La. It was setup to accommodate refugees from Burma who fled political prosecution. Eventually, she and her family managed to move to the United States.
