Kourtney Kardashian and Husband Travis Barker's Stepdaughter Atiana De La Hoya Show Off Their Butts in Cheeky String Bikinis: Photos

Atiana De La Hoya left little to the imagination in a collection of sultry bikini photos alongside Kourtney Kardashian.

The 27-year-old model posted photos from an Arizona boat excursion with her former stepfather Travis Barker's family on August 10.

De La Hoya showed off Kardashian's envy-worthy figure, with a snap of both of their butts on full display as they pranced through the dunes in thong bikinis, enjoying the summertime getaway.

"Adventuremaxxing," she captioned the images on Instagram.

For a solo shot, De La Hoya looked effortless as she flaunted her curves in a skimpy leopard print bikini against the desert landscape.

In other pictures, De La Hoya stared directly at the camera as she burst out of the water soaking wet. She adjusted her top with her cleavage on full display and bright red hair slicked back.

The 27-year-old showed off the picturesque landscape and her adventurous spirit with photos of her scaling cliffs in a matching workout set, with the eldest Kardashian nearby.

Fans were obsessed with De Le Hoya's vacation photos, with followers chiming in to praise her seemingly effortless summer style and Kardashian's age-defying figure.

"I see you carrying that wagon," one person tagged the 47-year-old.

"I was like, who’s thick a-- is that, it’s Kourtney," another mused.

"Simply beautiful…. Keep enjoying life to the fullest," a third shared.

Kardashian even reposted the carefree bikini shot to her own Instagram Story as she enjoyed the getaway with her husband's stepdaughter.

De La Hoya became Barker's stepdaughter after he married her mother, Shanna Moakler, in 2004. Moakler was previously in a relationship with De La Hoya's father and former professional boxer, Oscar De La Hoya.

Travis and Shanna split in 2008 after having two children together, Landon, 22, and Alabama, 20. Despite the divorce, both Travis and his kids have maintained a very close relationship with Atiana.

That relationship seems to have been extended to Kourtney, who married into the family in 2022. She shares children Mason, Penelope and Reign with ex Scott Disick.

Travis and Kourtney welcomed their son, Rocky, in 2023.

In 2023, Atiana's father credited Travis with stepping up to raise his daughter.

"Look, I didn't raise my kids, you know? Their moms did. And I have to give credit where credit is due," Oscar said to People.

"I'm grateful that Barker was there, you know, as a father figure for my daughter,” he added. “I have to be grateful that Shanna was a mother to Atiana, and just know my place, basically, you know? My place — I'm obviously a father, and I'm proud of it.”
