Her name is Maddie and Maddie found out who her guardian angel -- she found out Maddie had a guardian angel. We'll ask T.J. How it's going so far. Good morning to you, Strahan. Yes, this is the village that produced and supported that guardian angel you're talking about. These are the friends and family of this young man, jaelin and this is the guy they supported in making a decision to put his own health at risk in order to try to save the life of a young woman he didn't even know, had not met and still hasn't met but here's the thing, Strahan. She lives here and she doesn't know we're all outside so, jaelin, you stay here for just a second. I'm going to go in. Maddie is expecting me, however, Maddie and her family actually are gathered downstairs waiting on me to come in and say hello to them and Maddie and crew, hello, good morning. Hi. I was just talking about you, Maddie. Scoot over here. I'm going to be part of the family. I was just talking about you and what you've gone through at the age of 19. Yeah. And how you found a guardian angel that's changed your life and it's a story that we just had to tell. Her photos tell the story of a happy teenager but on the inside Maddie Ricci's body was slowly deteriorating? As soon as I would open my eyes, I would have a migraine. I was tired all the time. My knees always hurt. Reporter: She was diagnosed with lupus at age 12 and her life completely changed. Then at 18 after more complications, doctors told her she needed a liver transplant to survive. Madison had started really deteriorating quickly at the last semester of school. She was having a really tough time getting to classes some day. My liver was basically they call it cirrhosis. Reporter: Doctors suggested she try for a living donor and so her mom turned to social media. I just put out a Facebook post that my daughter needs a liver. I mean, that's what you do for your child is your child needs help and you help them so that was the best way I knew how. Reporter: They needed an angel. And 22-year-old jaelin Highsmith answered the call. He saw that Facebook post. Something just grabbed me instantly. I know if I didn't at least try it would not have sat right with me knowing I had the chance to do something. Jaelin waist match. I was in shock. I was speechless. We had no idea who the donor was at all. We knew it was a he. Reporter: After four months of testing in December the day finally came. The exchange between these two total strangers was a success. I was just blown away. Like I don't know this person and they saved my life. I just wanted him to know he's amazing for this and I can't wait to meet him. I want jaelin to know first off that I am going to squeeze him as hard as I can and thank him from the bottom of our heart, how grateful we are. How thankful we are that we have Madison now every single day for the rest of her life because of him of the he's our angel. He's our hero.

Thanks. Jaelin, you have been talking to me for the past couple of hours about -- You were here for a couple -- Yes. We've been outside for awhile. Yes. I held him hostage in an SUV.

Robin, this was -- this was a heck of a story in the making and they let us be here for it. They were going to meet at some point. We were happy we were able to facilitate it. I love how the mothers made a beeline for each other and gave each other a hug. That was priceless. Jaelin, let me ask you this, I know that you saw on social media and you said that not many people get a chance to literally save somebody's life so what was the bottom line for you like what made you want to do this? I think for me the bottom line was the opportunity was there and there's no way I could pass it up. I knew from day one that if I was able to do this then I would do it and, you know, god blessed me and Maddie as well and I was a match and it all worked out perfectly. I'm very grateful for that. Angel. This question, I have the question for the moms, Tracee and Kris.
