What she didn’t have, though, was the greatest health. She’s long battled Lupus, an autoimmune disease. She first announced she had Lupus in 2015.

What she revealed Thursday edged her a little further into “she has it all” territory.

Gomez said she had a kidney transplant this past summer and even more special, the organ was donated by her best friend, Francia Raisa, who turned out to be a perfect match.

The singer/actress revealed her news on Instagram. Fans wondered why she wasn’t out and about much promoting her new music.

“I’m very aware some of my fans had noticed I was laying low for part of the summer,” she wrote, “and questioning why I wasn’t promoting my new music — which I am extremely proud of.”

She thanked her fans for their support and for standing by her. And then she thanked her friend Francia for “the ultimate gift.”
