She’s a cool mom.

Kourtney Kardashian flaunted her curves in a tiny bikini while vacationing with her husband, Travis Barker, and their blended family.

The Poosh founder, 47, rocked the metallic two-piece while standing in the middle of a desert landscape with her hands up in the air via an Instagram photo dump on Saturday.

She also sported the cheeky swimwear while posing with Atiana De La Hoya, who wore a black swimsuit.

Other photos showed Kardashian wearing a leopard-print bikini, accessorizing with a double cross necklace and sunglasses.

The family also enjoyed some time on a boat, as Travis’ son Landon Barker was seen lounging while cruising on a river.

Kardashian also shared a video of her daughter, Penelope Disick, waving to her from a different boat, and a photo of her son Mason Disick hiking with a backpack.

An adorable snap showed Travis cuddling with his and Kardashian’s 2-year-old son, Rocky Thirteen Barker.

The group appeared to be active during their getaway, with photos showing them partaking in outdoor rock climbing and water sports.

“big family vacation girl,” the “Kardashians” star captioned the snaps.

Kardashian shares Mason, 16, and Penelope, 14, with her on-again, off-again boyfriend, Scott Disick, whom she officially split from in 2015 after nine years together.

The exes are also the parents of 11-year-old son, Reign, who wasn’t photographed on the getaway.

As for Travis, he shares Landon, 22, and daughter, Alabama Barker, 20, with his ex-wife, Shanna Moakler, whom he was married to from 2004 to 2008.

Atiana is notably the daughter of Moakler and boxer Oscar De La Hoya. However, the musician helped raise the now 27-year-old model.

Travis and Kardashian tied the knot in 2022.
