Should I tell the Mom a girl is texting a boy in Egypt?

A 16 year old girl is texting a boy in Egypt. She says she has checked him out on facebook and is legit. He has sent her pictures of him in Alexandria, and she has sent him at least one picture of herself. Likely more. She does not want me to tell her mother as she is sure he is ok. Their conversations do seem like teen chatter, thought she met him on chatous. I tell her not to believe everything and she smiles real big and says she can handle it--trust her. Yesterday she even spoke to him via the net, I'm not sure how that works, but she needed the country code to do it. Help! I don't want to betray her trust, but I am worried!
