'That would be nice': Kristin Cavallari admits to mull over BF Mark Estes' proposal of welcoming a baby together

LOS ANGELES, CALIFORNIA: Kristin Cavallari has expressed interest in becoming a mother again.

The 37-year-old shared a clip on her Instagram from her 'Let's Be Honest' podcast, where she spoke about her relationship with boyfriend Mark Estes, disclosing that she's been thinking about adding a new member in their family.

The reality star is already mother to sons Camden, 11, and Jaxon, nine, as well as daughter Saylor, eight, whom she shares with ex-husband Jay Cutler.

"I'm not actively thinking about it, but it's definitely in the back of my mind, is, you know, he wants to have a kid," Cavallari began per People Magazine. "I'm mulling it over."

Her friend Justin Anderson said, "I see you having another kid. And my goodness, could you imagine that baby?" to which Cavallari teasingly responded "That's why I might have to do it."

"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, according to the outlet.

Cavallari shared a picture on her Instagram Story of Estes walking and talking with one of her sons in March.

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," the 'Laguna Beach' star continued, per the outlet. "My kids really wanna see me happy. And I've been really good about separating my dating life from their life."
