The photo shoot, which took place on Monday, featured Kristin wearing a flowy dress with country-style accessories and cowboy boots while Tyler -- who competed on Season 15 of The Bachelorette starring Hannah Brown as well as Fox's The Real Dirty Dancing -- sported a plain T-shirt, jeans and work boots.
In one image, Tyler and Kristin stared longingly at each other from across the set, and then the photographer snapped a photo of the pair embracing, with Tyler's hands on Kristin's waist.
At one point, Kristin reportedly stood on her tiptoes and appeared to kiss the aspiring model and former Florida general contractor.
Kristin -- who also posed in sexy yellow leather shorts and an orange cropped vest -- reportedly enlisted Tyler to appear in her new campaign and the photos were taken at Joshua Tree in Palm Springs.
Once the snaps surfaced on the Internet and made headlines, Kristin played into the hype regarding her relationship with Tyler and their potential for romance when she uploaded an Instagram photo of herself straddling a man -- presumably Tyler -- while sitting on a window sill.
It's likely Kristin is just trying to drive attention to her new clothing and accessories line, but the kissing pictures came only one day after Kristin revealed she's ready for a new relationship following her broken marriage to former NFL player Jay Cutler.
The "Balancing in Heels" author is in the middle of her divorce from Jay and it has yet to be finalized. The former couple shares three children together: sons Camden, 9, and Jaxon, 7, as well as daughter Saylor, 6.
Kristin, who found fame when she starred on Laguna Beach, told her followers on Saturday that she's ready to begin dating again after spending the last two years of her life single and focusing on herself.
"I've honestly needed the past 2 years to work through some heavy stuff," Kristin said via Instagram, Us reported.
"I dated a little here and there but no one serious. I am finally in a place where I'm ready for a relationship. When you are able to finally fully close a chapter, it's amazing what you will start to attract."
She added, "I still very much believe in marriage and I've had tremendous growth over the past 2 years so I will be entering a new relationship as a different person which really entices me."
Following her split from Jay in April 2020, Kristin was linked to comedian Jeff Dye and singer Chase Rice.
"Jay and I actually went on a couple of dates, like, months and months and months ago," the Uncommon Beauty founder told Kaitlyn Bristowe during an October 2021 episode of her "Off the Vine" podcast. "But then I was, like, it's not there for me anymore."
But Jay is reportedly having a harder time moving on from his marriage.
