In the middle of her concert Saturday night in Miami, the "Come and Get It" singer took a moment to honor The Voice singer with a special dedication.
"One thing about Christina and her family is that she holds her faith so closely to her," Selena shared with the crowd before wiping away tears. "I think it's not about a religion and it's not about good deeds. I think she just had faith and I don't really understand how this really happened, but I would like to dedicate this song to her."
The singer then headed to the piano where she delivered an emotional performance of "Transfiguration."
Selena's concert comes just hours after the star posted a throwback photo of herself having fun with her good friend. "My heart is absolutely broken," she captioned the picture. "I miss you Christina."
