Kristin Cavallari and Boyfriend Mark Estes Pack on the PDA During Romantic Greece Vacation: ‘I Love You’

The couple, who went public with their relationship in February 2024, vacationed together in Santorini

Kristin Cavallari and Mark Estes are head over heels for each other in Greece!

The Hills alum, 37, and her boyfriend have been enjoying quality time together in Santorini, along with sharing snaps of their getaway on social media. On Monday, Aug. 5, the Montana Boyz TikToker, 24, posted a series of sweet shots that included some PDA with his girlfriend during their trip.

In the first slide, the couple are all smiles as they stand side by side in front of a stunning sunset. The Aegean Sea sparkles in the background while the couple pose in front of an infinity pool.

Following a second candid shot of the pair, Cavallari and Estes then go in for a passionate kiss in the last slide.

“I love you,” Estes captioned his post, which he originally wrote in Greek. Cavallari responded with a teary-eyed emoji followed by a white heart in the comments.

The former reality star also shared an inside look at their romantic getaway on her Instagram Stories, which included a shot of her rocking a black bikini next to her shirtless beau as they soaked up the sun together.

In the next slide, the pair stand in front of the serene landscape as the caption reads, “Until next time, Greece.” It was followed by another snap of the island setting that Cavallari captioned, “Santorini has the best sunsets I’ve ever seen” in white text.

The mom of three — she shares sons Camden, 11, and Jaxon, 10, and daughter Saylor, 8, with ex-husband Jay Cutler — also posted a carousel of photos earlier in August that showed off some of the activities she and her boyfriend did together.

Included in the mix were shots of the pair walking the cobblestone streets together, dining by the sea, and sharing another kiss at a restaurant.

Estes and Cavallari first went Instagram official in February 2024 after the Uncommon James founder shared a photo of the couple vacationing in Mexico together.

Later that month, a source revealed to PEOPLE that the pair had been "dating longer than people think" but "have kept it very private."

The source also added that the two met on “social media,” and Estes later confirmed that he reached out to his now-girlfriend first.
