Kristin Cavallari flaunts her toned figure in bikinis during European summer vacation

The "Laguna Beach" alum enjoyed a European getaway with longtime friend Justin Anderson after opening up about her recent dating life.

Cavallari kicked off the carousel aboard a boat with longtime friend and celebrity hairstylist Justin Anderson.

The "Laguna Beach" alum smiled while wearing a black triangle bikini as Anderson leaned in beside her. Rocky cliffs and crystal-clear blue water surrounded the pair as they enjoyed a day on the Mediterranean.

Another snapshot captured the former reality star posing barefoot on a dock overlooking the water.

She paired a blue floral bikini top with a white crochet mini skirt and a navy baseball cap while Anderson stood behind her in a white button-down shirt and a blue baseball cap. Turquoise water stretched out behind them as the pair posed near a ladder leading into the sea.

Away from the beach, Cavallari slipped into a white floral maxi dress while posing on a stone walkway surrounded by manicured gardens and towering mountains. She completed the look with a light-colored handbag and white sandals.

The carousel also included an evening stroll through a historic village.

The 39-year-old smiled while wearing a sheer white crochet cover-up layered over a white swimsuit, accessorizing the look with layered necklaces, bracelets and a woven handbag as she stood beside a centuries-old stone canal.

One of the images featured Cavallari posed up next to Anderson and Austin Rhodes - as well as "Southern Charm" star Austen Kroll.

The vacation photos briefly fueled relationship speculation in the comments, with some fans wondering whether Cavallari had a new romance with Kroll. 

"Okay spill the tea - are you dating @krollthewarriorking & how does @caconover feel about this?!" one user commented, referencing former "Southern Charm" stars Kroll and Craig Conover.

Others were quick to shut down the rumors, noting that Cavallari had already clarified on her Instagram Stories that they were simply friends.

"No one here watched her story yesterday - they are just friends
