【En la intimidad】

Selena Gomez has often taken a candid approach to discussing her struggles with lupus. On Thursday,En la intimidad she shared another part of her personal life, revealing that she underwent a kidney transplant this summer.

The actress and musician told her story though an Instagram post thanking her family, her team of doctors, and fellow actress Francia Raisa (of The Secret Life of the American Teenfame) for donating a kidney.

"She gave me the ultimate gift and sacrifice by donating her kidney to me," Gomez wrote. "I am incredibly blessed. I love you so much sis."

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. Until then I want to publicly thank my family and incredible team of doctors for everything they have done for me prior to and post-surgery. And finally, 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. I am incredibly blessed. I love you so much sis. Lupus continues to be very misunderstood but progress is being made.
