Kourtney Kardashian posted throwback bikini photographs from a family vacation to Italy on Saturday, taking her fans on a trip down memory lane.

Kourtney Kardashian’s 2019 bikini physique is on full display in throwback photos

The 44-year-old reality actress, who is married to the 47-year-old rocker Travis Barker, posed on a boat in the Mediterranean, baring her toned abs in a white and back bikini.

She used a straightening iron on her long, dark hair and covered her head with a white Panama hat to avoid sun damage.

Next to the Instagram slideshow, Poosh’s creator wrote, ‘Portofino, Italy August 2019,’

In other images, the beauty can be seen lounging on the boat in a daring black one piece with French cut legs and a scoop neck.

With a sly grin on her face, she flipped over to show off the low back and high cut bottom of the suit.

The reality show actress posted a mirror selfie of herself wearing distressed jeans and a bra adorned with a photo of the ancient Italian city.

Kourtney posted adorable photos of Penelope, 10, and Reign, 8, celebrating the occasion with their mom in the city where they would get married three years later.

Penelope’s red and white flowery clothing made her seem adorable as she posed with a dog.

She eventually played the role of the responsible older sibling by toting her younger brother through the city on her shoulders.

At the time, Penelope wore her hair in a bob, while Reign wore his down to his waist.

Penelope, Reign, and Mason, 13, are the children of the Lemme founder and her ex-partner, Scott Disick, 40.

They now have a blended family with Travis’ three children from his marriage to model Shanna Moakler, 48, who are Alabama, 17, Landon, 19, and Atiana de la Hoya, 24.
