The most beautiful moment of Selena Gomez's concert in Miami last night was when she dedicated a song to Christina Grimmie. She said: "When she was 14, we met her – my parents and I signed her, and one thing about Christina and her family, is that she holds her faith so closely to her. It's not about her religion, and it's not about good deeds. It's just that she had faith. And I don't really understand how this happened, but I would like to dedicate this next song to her.
