So fans were starting to wonder why Selena Gomez wasn't out promoting her new music this Summer. No need to wonder anymore because Selena dropped some huge news while we were all sleeping via her Instagram account. 

It's no secret that she's been battling lupus for the past few years. She's even had some pretty bad flare ups too. Lupus is a chronic inflammatory disease that makes your immune system attack your organs. It can focus on attacking certain systems like joints, skin, kidneys, blood cells, brain, heart and lungs.

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.

And her best friend was the donor to provide the kidney to Selena! What an great story! 

I'm shocked that she was able to have this surgery without anyone letting it get out to the public. 

As She mentions in her Insta caption, "Lupus continues to be very misunderstood but progress is being made.

Hopefully Selena's celebrity status can help get more attention and research on helping those battling Lupus.
