Kristin Cavallari has gone Instagram official with her hunky new boytoy.

The reality TV star, 37, is dating 24-year-old model Mark Estes — three years after she divorced NFL star Jay Cutler.

On Tuesday, the mother-of-three shared a photo of herself cozying up to Mark during their getaway in Los Cabos, Mexico.

In the caption she declared: ‘He makes me happy’

Mark re-posted the photo to his Instagram Story and included two red-heart emojis.

According to TMZ, the duo have been hanging out for about a month but things aren’t serious yet.

Sources told the outlet that Mark and Kristin ventured to Mexico together last week and that they were ‘showing a lot of PDA’ on the flight over.

Kristin was there to work on her jewelry line Uncommon James.

Along with modeling, Mark was a football player at Montana State University.

According to the college’s website, he played wide receiver.

He is also part of the Montana Boyz, a TikTok collective with nearly 460,000 followers.

As of now, it’s unknown how Kristin met the Montana-born stud but they are both based in Nashville, Tennessee.

Kristin lives in a $5.5million house that she purchased after divorcing Cutler in 2020.

The former couple share three children: Camden, 11, Jaxon, nine, and Saylor, eight.

She was married to Cutler, former quarterback for the Chicago Bears, from 2013 until they split in April 2020, with their divorce finalized in June 2022.

In a 2022 interview with Call Her Daddy, Kristin described her relationship with Cutler as ‘toxic.’

She told host Alex Cooper that she was ‘really unhappy’ and in an ‘unhealthy relationship’ and didn’t want her kids to think that ‘was normal.’

Kristin said that ending their marriage was ‘really scary’ and a decision that took her ‘a few years to to actually pull the trigger.’

‘It was just time. Nothing major happened. At the end, it was just time.. It’s the scariest thing. It’s always the saddest thing. I mean, it’s so many emotions, but it can also be the best thing.’

She said she doesn’t regret anything and is ‘thankful’ for their time together because of their three children.

After the split, Kristin put herself back in the dating game.

She was linked to standup comedian Jeff Dye, 41, for five months before calling it quits in May 2021.

His attempt to rekindle things last October went terribly wrong as Dye, who is now sober, was arrested for DUI after he crashed his car into a tree on the way to meet Kristin for coffee in Los Angeles.

Kristin’ most recent fling was with The Bachelorette alum Tyler Cameron, 31.
