Singer Selena Gomez says her kidneys were "done" when she had the transplant operation, and credits her best friend for saving her life. In an interview with <em>The Today Show</em>, the pop star, who has battled with autoimmune condition lupus, said it got to the point where it was "kind of life or death", reports <a href="http://www.mirror.co.uk/3am/celebrity-news/selena-gomez-says-could-died-11421339">mirror.co.uk</a>. Earlier this year, the singer, 25, revealed that her friend Francia Raisa had donated one of her kidneys to her in a secret operation. In their first joint interview since the surgery, Gomez said: "My kidneys were just done." She added: "That was it and I didn't want to ask a single person in my life and that was the day I came home when I found out and she volunteered and did it." Asked: "You feel like Francia saved your life?", the singer responded: "Because she did. That's it." Gomez revealed the news of her operation on September 14 by sharing a photograph on Instagram of her and Raisa lying side-by-side in their hospital beds holding hands. She wrote: "I'm very aware some of my fans had noticed I was laying low for part of the summer and questioning why I wasn't promoting my new music, which I was extremely proud of. So I found out I needed to get a kidney transplant due to my Lupus and was recovering. It was what I needed to do for my overall health. I honestly look forward to sharing with you, soon my journey through these past several months as I have always wanted to do with you. "...There aren't words to describe how I can possibly thank my beautiful friend Francia Raisa. She gave me the ultimate gift and sacrifice by donating her kidney to me." _________________<br/> <strong>Read more: </strong> _________________
