Selena Gomez got teary-eyed in her first television interview since revealing her kidney transplant surgery in September. The singer sat down with NBC News alongside her best friend and kidney donor, Francia Raisa, for an interview that will air on Today on Monday and Tuesday of next week.

My kidneys were just done, Gomez told anchor Savannah Guthrie after she appeared to wipe a tear from her eye.

When Guthrie asked why Gomez, 25, feels like Raisa, 29, saved her life, the singer and actress responded simply, Because she did. Thats it.

Gomez revealed she had a kidney transplant last month, sharing a photo of herself and Raisa together in the hospital.

So I found out I needed to get a kidney transplant due to my Lupus and was recovering, the Fetish singer wrote in the caption, noting, it was what she needed to do for my overall health.

There arent 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.
