Pop star and all-round sweetheart Selena Gomez has revealed on Instagram that her recent career break was because she had to have a freakin’ kidney transplant.

The 25-year-old was diagnosed with the autoimmune disease lupus in 2013, and has received numerous treatments for it, including chemotherapy. She announced last year that she was taking a break to focus on her health; today, she explained that she had needed the time to recover from the major surgery.

The surgery was obviously a success, with Gomez posting pictures of her healing scar from the operation.

Touchingly, it was a friend of Gomez who donated the transplanted kidney – a girl called Francia Raisa. Gomez used her post to express her thanks for Raisa’s “ultimate gift“:

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.

Wishing you all the best with your recovery, Selena! You’re a real inspiration to us all.

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.
