Kourtney Kardashian has been trolled after she bared all as she went for a dip with boyfriend Travis Barker in the ocean rocking a black Gucci thong.

The couple blissfully happy as they packed on the PDA and went swimming in Fruttuoso, Italy‎, on the Italian Riviera between Camogli and Portofino.

After arriving to the remote town in Genoa on a small boat, the 42-year-old reality star and Barker, 45, were seen cuddling on a lounge chair.

While they have previously traveled with their children or family, none of their children appeared to be present on their romantic trip.

Leading to some shady social media commenters to criticize her rather revealing choice of swimwear.

"Oh my goodness...she may as well be naked," one person wrote online.

"I honestly don't think any woman should be wearing dental floss on the beach - out of respect for other people. Around your own private pool is one thing; in public - no," a second added.

"I am so over seeing women's bare naked a.z.z.es flaunted everywhere. No matter what size or shape. We all have our own. Why do these women think we are sooo over the moon excited to see their bare nakedness? Flaunting your bare nakedness covered by nothing more than a string of dental floss, is nothing but a cheap and trashy. Ugh!!" a third commented.

The mom-of-three was previously criticized after she allowed her eldest child, daughter Penelope Disick, to dye her long brown hair a deep red. The 42-year-old Keeping Up With The Kardashians star shared an image of her baby girl, aged nine, as she stood in the family's Calabasas, California mansion.

The Poosh founder captioned the snap with red emojis including a strawberry, fire, watermelon, cherries, apple and heart.

Penelope, whose father is Scott Disick, had on a black T-shirt that said Slayer on the front.

The only daughter of Kourtney and Scott posed with bare feet as she closed her eyes and touched her head.

Although Penelope seemed perfectly happy and content in the photos, some shady social media commenters felt the hairstyle was "inappropriate" for a girl her age.

"A nine year old should only be thinking about playing, not her appearance or hair colour. How very sad," one person wrote online.

"For someone who's so health conscious and doesn't allow candy at a kids candy land themed birthday party... dumps chemicals in her 9 year old daughter's hair! She's lost the plot that woman," a second added.

"My 10 yr old granddaughter's hair was dyed multi colors by her mother. I don't think little children should have their hair dyed. My granddaughter didn't want it done and was sorry her mother did it. She had to had her hair reduced brown to cover it up and now her hair looks like it's fried. The child is 10, not 17 yrs old. Stop this fad," a third commented.
