Selena Gomez and The Weeknd can literally say they’ve been through it all after he stayed by her side as a huge support following her kidney transplant.

Gomez received the surgery after she experienced complications from Lupus, a chronic autoimmune disease.

The Weeknd, whose real name is Abel Tesfaye, was one of her biggest supporters.

“Abel has been one of her biggest supports,” the source told PEOPLE Friday. “She had been traveling with him on his tour and he was off during her surgery and right after during her recovery. He’s been very caring and it’s meant a lot to her to have him by her side.”

Gomez’s good friend Francia Raisa donated her kidney to Gomez. The singer took to Instagram to share her healing process with fans Friday.

She posted a snapshot of her and Raisa holding hands as their hospital beds sat next to one another.

“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 new music, which I was extremely proud of. So I found out I needed a kidney transplant due to my Lupus and was recovering,” she wrote. “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.”

She went on to thank her close friends, family, and of course Raisa.

“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,” she continued. “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.”

She went on to let fans know how they can stay educated about the condition.
