"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," she began in the humble post.
"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. I honestly look forward to sharing with you, soon my journey through these past several months as I have always wanted to do with you. Until then I want to publicly thank my family and 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," she continued. Lupus continues to be very misunderstood but progress is being made.

Gomez's PDA with The Weeknd:
Sometimes, an Instagram feed is a reminder of what has changed in someone’s life. For Gomez, that blast from the past happens to be one of the top-liked pictures of 2017.
In this post, which earned 8.1 million hearts, Gomez and former boyfriend The Weeknd pose in their sunnies with arms wrapped around one another as they attended Coachella in April.
The photo told a thousand words, apparently, because the singer didn’t bother to caption the post.
Another Gomez/The Weeknd memory:

Now that Ronaldo is a dad of four, he's just over halfway finished, he admits. When asked how Cristiano Jr. was handling all the new babies, Ronaldo replied, "He’s doing well and says he wants more brothers and sisters. He wants seven, the magic number, and I think that’s good."
Gomez's risque bike ride:
Gomez returns to the list yet again, this time for a bikini-clad bike shot for her Vogue cover in March.
Captions are clearly optional for the pop star; she didn't include one with this particular photo, but she did share some insights in other photos from the shoot.
"Ok freaking out a little. Thrilled to share my first American @voguemagazine cover with you!" she wrote alongside the cover shot. "I want to thank Rob Haskell for writing my story. I was a little nervous at how honest I was but you depicted where I'm at perfectly. I'm so grateful," she added with another photo.
The sexy shot of the pop star earned her the ninth spot after shoveling in 7.1 million likes.
Gomez's birthday wishes:
Rounding out the list is another shot of Gomez, this time celebrating her quarter-century birthday. In the fun photo, the singer and actress posed on the kitchen counter surrounded by balloons and overlooking two cakes sparkling with lit candles.
"Thank you for all of my bday love. I couldn't be more blessed. A lot of you don't realize how much you mean to me. I. Love. You. -- think 25 is going to be epic. xo," she expressed in the caption.
