Gomez's pal, Francia Raisa, was the one to donate a kidney to the singer. Shortly after her transplant, Gomez opened up about the experience in an interview with the Today show.
"My kidneys were just done. That was it, and I didn't want to ask a single person in my life…That was the day I came home and I found out. And [Raisa] volunteered and did it," she said. "I guess I got to a point where it was really life or death."
In an interview with ET last year, Raisa said her decision to donate her organ to Gomez was "very faith-based."
"It just kinda happened coincidentally, but I don't believe in coincidences. I believe that that's God's way of remaining anonymous," she said. "I'm very grateful for the opportunity."
