Kevin Costner is Kristin Cavallari's "forever crush"

During an Instagram Story Ask Me Anything, Kristin was asked: "Can you just go on a date with Kevin Costner already?"

The blonde beauty - who has Camden, 12, Jaxon, ten, and Saylor, nine, with ex-husband Jay Cutler - subsequently joked about her celebrity crush.

Kristin - who is currently single after splitting from TikTok star Mark Estes earlier this year - said in a since-deleted story: "Give him my number. Forever crush."

Meanwhile, Kristin recently insisted that she won't waste her time dating the wrong person.

The reality star revealed that she won't hesitate to end a relationship if she sees it's not working.

Kristin said on the 'Let's Be Honest' podcast: "Where I'm at in my life, if I feel one thing is wrong, is missing, I'm not wasting my time or my energy on someone."

The 'Very Cavallari' star has no interest in "playing a game" in her love life, and she's willing to be brutally honest with her partners.

She said: "I'd rather just be an adult and have an adult conversation, and be like, 'Hey, here's where I'm at,' and just end things. So that's done.

"And I do think if the right person came along, I would be ready to date, but I'm not actively looking to date right now."

Kristin is determined to be decisive about her love life. But her ruthless attitude has stunned some of her friends.

She shared: "Even sometimes my friends are like, 'Jesus. OK.' Like, there's no chill. I'm like, 'No, this isn't working for me.'"
