Back in September, Gomez revealed she received a kidney transplant due to her struggle with the autoimmune disease Lupus, updating fans on why she spent much of the summer under the radar. The star shared a sweet photo on Instagram that featured the friends holding hands before the procedure, as well as a snap of the healing scar on her stomach.
"I found out I needed to get a kidney transplant due to my Lupus and was recovering," the star wrote. "It was what I needed to do for my overall health."
She continued, thanking her family, her "incredible" team of doctors and most of all, her dear friend.
"There aren’t words to describe how I can possibly thank my beautiful friend Francia Raisa," Gomez added. "She gave me the ultimate gift and sacrifice by donating her kidney to me. I am incredibly blessed. I love you so much sis."
Watch the interview with Gomez and Raisa in full when it airs in a two-part installment Monday and Tuesday on the Today show.
