The singer and actress shared the information via her Instagram page.
“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.
“Until then I want to publicly thank my family and the 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.’’
We can only wish her a speedy recovery.
