Madison and Kelley used to be best friends!

Madi shared that Kelley was her closest friend in the Bachelor mansion, and they remained incredibly close after the show ended. "She was in group messages with me and my family. I mean, we were really close and talked, like, 24/7."

As Madi put it, "we walked through so much together and, you know, like, that was a friendship that I thought was gonna... I thought she was gonna be in my wedding, ya know? I thought we were gonna be best friends for life."

Kelley never told Madison about her rekindled relationship with Peter.

Madi said, "It was really confusing to me when I saw that and just that, I don't know, that I didn't receive any kind of like a heads up or any sort of, ya know, a text or an explanation of why."

She didn't find out that they were even in communication until she saw, along with the rest of Bachelor Nation, that they were out and about together in Chicago during the ongoing nation-wide quarantine.

To make matters worse, the photos of Peter and Kelley together surfaced ON MADI'S BIRTHDAY.

Madi was clearly hurt by this, saying "He didn't text me on my birthday. She didn't text me on my birthday."

Just days before he was spotted with Kelley, Peter was telling Madison he wanted to be with her.

Madison told Kaitlyn: "What was really confusing to me was that two days before he was spotted in Chicago, he was, like, calling me and texting me and being like 'I miss you, let's get back together.'"

Madison has heard rumors that Kelley and Peter got together a LONG time ago, and it sounds like she believes them.

"I had heard things and I actually asked Peter about some of the things that I'd kinda been hearing, rumors about him and Kelley while we were still trying to figure our thing out," she said. "... just that there had been hangouts and meet-ups and conversations that had been going on while he was still with Hannah Ann and while he was also trying to figure things out with me. And I asked him those questions and I think it's, ya know, very interesting because his answers and her answers very much contradict the current situation that's happening right now."

Madison and Kelley's friendship appears to be over for good.

She told Kaitlyn: "I haven't spoken to her in a really long time."

After EVERYTHING, Madi wishes both Peter and Kelley the best.

"I saw something special in Kelley, that's why she was my best friend... I want the best for the both of them."

Talk about taking the high road.
