Her friend Justin Anderson responded, "I see you having another kid. And my goodness, could you imagine that baby?"

"That's why I might have to do it," Cavallari teased in response.

If she were to get pregnant again, Cavallari said this time would be different because she has a bigger support system.

"But my kids are old enough now where they can help. That would be nice. If he ends up really being the one, I would have a kid," the mom of three said.

"Are you for real thinking about this?" asked Anderson.

"Yeah, I have to. I mean, yes. It's become pretty serious, this relationship I would say," Cavallari shared.

In March, Cavallari shared a picture of her Instagram Story of Estes walking and talking with one of her sons. She simply captioned the image with a white heart, shared below the pair's backs.

The photo came only a few days after Cavallari revealed on her podcast that her kids had met Estes, whom she calls "Montana" after his Montana Boyz TikTok group.

"This is the real first guy I'd say they've met. When Montana came to pick me up, the boys were like, 'Can I show you my room?' Like, Montana's upstairs with my kids, seeing their rooms. My boys were so excited about him," she said on the episode.

"I think more than anything, my kids were really excited for me," she continued. "My kids really wanna see me happy. And I've been really good about separating my dating life from their life."
