The 37-year-old reality TV star was posing in a white crop top and matching shorts as she modeled a red Santa hat.
The image was shared to her two company Instagram pages: they are Uncommon James Jewelry and Uncommon James Skincare.
Earlier this month she said on her Insta Stories that she had a ‘forever crush’ on the Yellowstone actor.
Costner played Montana ranch owner John Dutton for five seasons until he walked away from the series.
She also told a follower she wants to start a romance with the newly divorced movie star soon even though she has said in the past she was no longer going to date Hollywood men.
‘Give him my number,’ she replied on Sunday, calling the actor, 69, her ‘forever crush.’
There is a 32 year age difference between The Hills star and the movie icon.
Kevin is single since divorcing wife Christine Baumgartner.
They had a nasty split that involved fighting over money.
Since leaving Christine, the Oscar-winning actor and director has been linked to singer Jewel, Sharon Stone, whom he flirted with at a party, and Mad Men star January Jones.
It appears, however, that he has not been in a romance with any of these beauties.
That means Kristin has a shot at dating the Dancing With Wolves star.
This comes weeks after the siren said she is ‘dipping her toe back in the dating pool’.
The TV star split from Mark Estes in September, and Kristin has admitted that she’s already returned to dating.
The outspoken star said on her Let’s Be Honest podcast: ‘Here’s my thing. I think I’m just so f****** over Hollywood in general.
‘I’m having people reach out to me right now, and I’ve had a couple, like, big people in Hollywood reach out to me…
‘But there is nothing in me that wants to go out with these people. Whereas three years ago, I would have been like, “Okay. Yeah.”‘
The star who used to be wed to Jay Cutler and once dated Nick Lachey, Nick Zano, Matt Leinart, Chase Rice and James Dye, did not name the famous men who want to wine and dine her.
Kristin previously insisted that the 13-year age gap between herself and Mark wasn’t an issue. But she’s now keen to date someone her own age, and ideally, someone with a lower profile, too.
The ‘Very Cavallari’ star said: ‘I wouldn’t say it’s a deal breaker, but I am not looking to date anyone in entertainment. And, like, I will never date anyone from the DMs ever again because it attracts the wrong type of guy.’
Kristin was married to former NFL star Jay Cutler between 2013 and 2022. And the reality TV star remains open to the idea of tying the knot again.
Kristin – who has Camden, 12, Jaxon, ten, and Saylor, eight, with her ex-husband – said: ‘I’m telling you right now … My next boyfriend is gonna be my next husband. Okay? I’m already putting that out there.
‘I can’t keep dating. Like, I am dating, but, like, I can’t keep doing it.’
Kristin announced her split from Jay in 2020, when the former couple released a joint statement.
They said on Instagram at the time: ‘With great sadness, after 10 years together we have come to a loving conclusion to get a divorce. We have nothing but love and respect for one another and are deeply grateful for the years shared, memories made, and the children we are so proud of.
‘This is just the situation of two people growing apart. We ask everyone to respect our privacy as we navigate this difficult time within our family.’
This comes after the mother-of-three shared on her podcast that she is a very small 114lbs at 5ft3in.
Cavallari was discussing her weight when revealing she was so unhappy being married to Cutler, 41, her husband from 2013 until 2022 that she got down to 102lbs.
The TV star was ‘very thin’ due to stress from the ‘unhappy’ union that resulted in three children.
Cavallari made her comments during her Let’s Be Honest podcast.
The Laguna Beach star was asked by a fan how she looked so thin when making Very Cavallari, which aired from 2018 to 2020.
‘I was very thin. I’ll put it in perspective for you guys. I’m 5’3′. I currently weigh 114lbs. Filming Very Cavallari, I got down to 102lbs and I was eating the same amount of food that I’m eating now,’ she explained.
Cavallari admitted that the marriage made her stress out.
‘The difference was I was so unhappy and so stressed out,’ she explained.
‘I look back at photos from that time period and I am like, ‘Holy s**t!’ I was rail f***ing thin. I was skin and bones. I looked like s**t,’ she admitted.
‘I think I look so much better now. And you guys, that was just stress. That was being in a really unhappy marriage, quite honestly. Literally, I was so unhappy and I had way too much on my plate.’
And the jewelry designer added she thinks she is better off at 114lbs.
This is not the first time Kristin has talked about her weight loss during her Cutler marriage.
In June 2022, she shared that she was happy with her figure after having added a few extra pounds.
