Selena Gomez Reveals Her Bestie Gave Her The Ultimate Gift: A Kidney

LOS ANGELES (CBSLA.com) — Pop princess Selena Gomez has it all -- youth, beauty, a rock star career, commercials, fame.

Bieber an ex, Weeknd a current? She's the envy of many. She's even in Taylor Swift's posse!

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."

Gomez wrote, "There aren't words to describe how I can thank my beautiful friend Francia Raisa...I am incredibly blessed. I love you so much, sis."
