Kristin Cavallari was "really let down" when she reunited with her childhood sweetheart

Speaking on her 'Let's Be Honest', she said: "It was a very impactful relationship in my life, and one that I've sort of held in this high regard all of these years and really looked at it as being really sweet and loving and just I've just always walked away with really good feelings about it.

"And mind you, leading up to it, Johnny and I had been talking. We reconnected, and we were talking for a few weeks, and he asked me the questions beforehand. Because he doesn't do this stuff normally. I gave him the questions. I was like, I get it, he's probably gonna be nervous, and I wanna make him comfortable and set him up for success.

"So Johnny comes up on stage, I'm so excited, and it was the complete opposite of how I had envisioned it going

"I felt like he was nervous, and so because he was nervous, how he decided to channel that was to essentially give me a hard time and put me on blast. And it really threw me. It was not what I expected. I was really let down."

The former 'Laguna Beach' star- who split from TikTok star Mark Estes towards the end of last year after seven months of dating - was "really upset" with her live interaction with Johnny, and has "never understood" why men in her life are so eager to put her down in public.

She said: "It was a very different person on stage from the person I had been talking to weeks leading up to it.

"And then the person who afterwards wanted to hang out and came up and gave me the biggest kiss on the cheek and was back to being so sweet and so kind. And what both of those instances did, was stirred up a lot of emotion about the guys that I've chosen in my life.

"Johnny on its own - I think I would have still been upset, maybe not to the degree that I was. Also being tired and it just being a long day and just giving so much energy, I was really upset. I think what it did was it made me realize how far I've come, and I'm talking specifically about guys.

"I've never understood why the men in my life publicly have always wanted to put me down."
