AceShowbiz - Kristin Cavallari and her boyfriend Mark Estes enjoyed their Grecian getaway. On Sunday, August 4, the reality TV star took to her Instagram account to share a glimpse of their romantic vacation.

In the new post, "The Hills" alum could be seen cutting a busty look in an orange knit bikini. She paired the look with a netted white sarong, gold jewelry, flashy watch and glossy onyx sunglasses.

One of the snaps featured Kristin and her beau locking lips while sitting at a table at a restaurant. For the occasion, Mark went all-white as he left his shirt unbuttoned. The 24-year-old beau matched his lady's style by wearing a pair of aviator glasses.

Kristin also included a photo of them looking smitten with each other with a beautiful sunset in the background. She additionally shared pictures of them posing with her close friend Justin Anderson and his boyfriend Austin Rhodes, who joined them for the trip.

The vacay came after the couple embarked on a family getaway to the Bahamas with her three kids in June. At the time, Kristin treated fans to a slew of photos of herself and Mark having fun with Camden, 11,  Jaxon, 10, and daughter Saylor, 8, whom she shares with ex-husband Jay Cutler. Their Bahamas getaway included swimming and playing with wild pigs.

Prior to that, Kristin revealed that Mark had already met her children in March. "This is the real first guy I'd say they've met," she spilled on her podcast, "Let's Be Honest with Kristin Cavallari".

It was said that the couple first met on social media, and it was Mark who initially reached out to her. The couple later went Instagram official in February 2024, when Cavallari shared a vacation photo from Mexico with the caption, "He makes me happy." Mark later shared it on his Instagram Stories with heart emojis.
