A sad news about Selena Gomez shocked her fans and followers.
She underwent a kidney transplant secretly over the summer.
The singer had been battling lupus since 2015.
The 25-year-old pop star had been open with her fans about this.
What is lupus?
It can be a fatal disease which affects the immune system.
Once the healthy tissues were affected, parts of the body will have inflammation.
In 2015, Selena assured fans that she's "very healthy" amid her battle with lupus, but admits she's still "uncomfortable" discussing her condition openly.
"It has been overwhelming and the response has been very supportive, which is nice - but it still makes me a little uncomfortable," she said.
"I waited for the right time to talk about it because I am in a great place and I'm very healthy. I'm not trying to be loud about it: It was time to use my platform to help."
