Kristin Cavallari Enjoys Bikini Sauna As Boyfriend Does The Dishes

Kristin Cavallari is showing Instagram that her summer has gotten off "to a good start." The reality star, 36, updated her account on Sunday with a gallery of snaps that featured her kids, her bikini body, and boyfriend Mark Estes. Kristin, who has made headlines for the age gap as she dates the 24-year-old former football player, had fans joking about how domesticated Mark is — it looks like the photo of him doing the dishes drove them right to it. Others, however, were likely eyeing up the rare family display, plus the MTV alum's fierce figure as she stripped down to swimwear to relax in a sauna.

Scroll for the snaps. Kristin, who rarely shows her children's faces on social media, included one of her brood swinging across a stream as she kicked off her gallery with a reminder of her motherhood — together with ex-husband Jay Cutler, she's a mom of three.

Fans also saw an outdoor workout with a trainer and one of Kristin's sons, but things quickly shifted to couples mode as the Uncommon James founder flaunted her budding romance with Mark.

Snapping a gym selfie as she posed by a shirtless Mark in one slide, Kristin flaunted her fit figure in a black sports bra and leggings set as she highlighted her fabulous figure, but it looks like fans were more interested in commenting on Mark. He was also featured in a slide showing him handling the dishes, with the sauna shot seeing Cavallari stunning in a stringy black bikini as she enjoyed her wellness session. "Summers [sic] off to a good start," she told her 4.8 million followers.

Fans seemingly aren't done poking fun at Kristin's younger boyfriend. "She's giving him chores just like another one of her kids lol," one replied. "Dude now a dad to 3 lol," another said.

Also popular was a fan saying: "If you get pregnant this summer you should name her summer." Kristin had gone public with model Mark in February of this year. Saying that it was a "little early to hard launch something" on her podcast, she added: "However, I feel very different with this man." Confirming that she's introduced kids Camden, Jaxon, and Saylor to Mark, Kristin continued: "I think more than anything, my kids were really excited for me. My kids really wanna see me happy."

Not all comments were mocking, though. "You give me hope that at our age I can find love and age doesn’t matter," one fan replied, adding a heart emoji.

In late February, Kristin shared this table selfie of herself with Mark as the two jetted out for a romantic vacation in Mexico. Fans did troll her, but they still left over 370,000 likes.
