More than five years ago, Selena Gomez received a second chance at life when Francia Raísa voluntarily donated a kidney to help with her close friend's Lupus battle. Now, the Same Old Love singer is reiterating just how selfless the act was from her "best friend." "I will never ever, ever be more in debt to a person than Francia," Selena shared on Apple TV+'s Dear… "The idea of someone not even second-guessing to be a donor was unbelievably overwhelming." Selena recalled the moment Francia agreed to get tested to see if she could be helpful. Within three days, the pair discovered they were a match. "It was one of those moments where I felt watched over. I know I was so lucky. I understand that that doesn't happen for a lot of people and I know the outcome of some of those situations and how serious they are, so I do not take it lightly that it's happened to me that way." Selena also publicly thanked Francia while accepting Billboard's 2017 Woman of the Year award at the event.
