Aeta Boy Singing Colbie Calliat Song!

This video caught my attention. The native boy sang Bubbly (Colbie Calliat's song) in exchange for a few coins in Subic, Zambales, Philippines. Who could ever resist his RnB-like voice? I wonder who this boy really is? I knew that he is Arjohn Gilbert. But is he really an Aeta? or Fil-Am abandoned by his black American army father? And now, he's making money on his own.
