Kourtney Kardashian shared sexy Christmas throwbacks on her Instagram page on Sunday night.

The 45-year-old star wore a cream bodysuit that flashed her chest, paired with colorful bottoms – while holding a giant snow globe.

She wore black feather gloves as she posed in front of the Christmas tree.

Kourtney also posted another throwback picture of herself wearing a Christmas onesie with red thigh-high boots.

The mother-of-four’s Instagram photo dump featured a number of Christmas pictures – mostly of her previous Christmas trees and Christmas decorations.

The star captioned the photo dump, “Hello December.”

Kourtney opted for a nude bodysuit with silver accents along the edge for a touch of sparkle.

She wore geometric patterned leggings in orange, gray and white that also featured a large nude bow along the waist.

The star styled the look with gloves and half-up, half-down hair.

She held a large snow globe in her arms for a cheeky snapshot.

The second sexy picture she shared was another busty look – a retro picture of her in a green, white and red one-piece.

The low-cut dress emphasized her cleavage in the look, paired with the eye-catching boots.

She styled it with red ornament earrings and her long wavy hair.

The star sat next to a Christmas tree and a few toys next to her.

The star posted a series of tree photos from the past few years.

She’s also known for her wild holiday designs, including an upside-down tree in her foyer.

Her throwback Christmas content comes just weeks after she celebrated her youngest son Rocky Barker’s first birthday.

Her son’s birthday party was Disney themed.

The birthday party was held at her family’s home – with Disney-themed treats and even a large carousel on the property.

Kourtney, a huge Disney lover, also enjoyed a trip to the Disneyland theme park in Anaheim with her family for her son’s birthday.

Paying homage to her vintage Disney-inspired “Baby Barker” sign that she had at her baby shower last year, Kourtney debuted the same sign at Rocky’s first birthday party.

The 45-year-old Poosh founder even enjoyed a trip to the exclusive Club 33 at Disneyland Resort – and also made a stop at Disney California Adventure Park.

Kourtney and Travis welcomed their first child together, son Rocky Thirteen, on November 1, 2023.

Rocky’s birthday party included two birthday cakes – including a large one with a Mickey Mouse silhouette and a smaller one with shredded coconut.

Kourtney has three children with ex-partner Scott Disick: sons Mason (14) and Reign (9) and daughter Penelope (12).
