Los Angeles - Selena Gomez has paid a glowing tribute to her long-time friend Christina Grimmie.
The 23-year-old pop star used the Miami stop of her Revival World Tour to speak of her love and affection for Christina, who was killed by a gunman following her concert performance in Orlando, Florida, on Friday.
Selena said: "When she was 14, we met her and my parents and I signed her.
"One thing about Christina and her family is that she holds her faith so closely to her. And I think it's not about a religion and it's not about anything or good deeds.
"It's just that she had faith, and I don't really understand how this really happened, but I would like to dedicate this next song to her."

In a statement, he told People: "Words cannot begin to describe the pain I am feeling.
"I learned this business through the eyes of a father and Christina was like a second daughter to me."
