(NBC) - Selena Gomez has revealed she is recovering from a kidney transplant.
The singer/actress posted photos on her Instagram account, saying that her longtime friend was the donor.
Gomez says the transplant was necessary because of her battle with Lupus an autoimmune disease.
One form of Lupus can trigger the immune system to attack the skin, joints, kidneys and even the brain.
It’s not uncommon for people with Lupus to develop kidney disease at some point in their lives.
It predominately affects women of childbearing age.
