Selena Gomez and Francia Raisa are ready to tell their story. 

The two sat down for the first time with Today’s Savannah Guthrie for an emotional interview set to air next week, months after Gomez received a kidney transplant from Raisa. As for why the pair, who revealed their surgery in September, waited to speak out about the procedure, a source tells ET that they wanted to make sure everything was on “their own terms.” 

"It was really hard for [Raisa] to keep this a secret. Paparazzi follow Selena everywhere and their friend group is really close, but Francia didn't tell anyone she was going to do this. It was a private thing between her and Selena,” the source says, adding that they “always planned to speak out about it, but wanted to wait until they had healed and they were in a place where they could share their story on their terms." 

In a promo for their Today show interview, Gomez is seen tearing up while talking about Raisa’s kidney donation. “My kidneys were just done,” Gomez says. “That was it, and I didn’t want to ask a single person in my life… and [Raisa] volunteered and did it.”

“She did [save my life],” Gomez continues. “That’s it.” 

According to ET’s source, Raisa only confided in a “few close friends after the surgery,” which left a very big scar. “It’s a huge scar. There’s three big incisions that transcend across her abdomen.” 

Months after recovery, however, the source says Raisa is “doing great and is right back to being her usual amazing self.”

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. 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. Lupus continues to be very misunderstood but progress is being made.

"Francia never second guessed her decision and has no regrets,” the source continues. “She's excited to share her story publicly now."
