Kourtney Kardashian showed none of the telltale signs of tiredness that comes with having a newborn at home as she stepped out for her family's annual star-studded Christmas soiree on Sunday night.

The starry-eyed reality star, 44, rocked a sultry look – sans pants – at the annual Kardashian-Jenner Christmas Eve party, which was held at sister Kim's estate this year.

Just seven weeks ago, the eldest Kardashian gave birth to baby boy Rocky with husband Travis Barker.

Kim Kardashian covered her lavish California mansion in fake snow for the star-studded bash, and her sister Kourtney definitely got the memo as she stepped out in a floor-length black fur coat.

The jacket was robe style and was tied around her waist with a tie that only revealed a corner of what was underneath…which wasn't much.

The Poosh founder wore sheer tights and a black bodysuit, opting not to wear pants or a skirt.

Kourtney beamed in social media videos from the party. Her raven locks were slicked back into a low side-parted ponytail and she stunned with her signature dramatic makeup.

The reality star gave birth to her fourth child and first with husband Travis Barker less than two months ago.

On Wednesday this week, the Poosh founder took a big step and began her “first day at the gym” since giving birth to baby Rocky.

She jumped to her Instagram Stories and shared that she's slowly getting back into her fitness routine, but reassured other moms that “it's not a race.”

While spending time on the treadmill, she typed: “7 weeks postpartum: first day at the gym, 30 minute run, incline 3.0 12.0…”

The mother of four added: “Take it easy, no rush, no pressure mums, your body is healing, it's not a race.”

Kravis shared a first look at her baby boy in sweet family vacation photos on the reality star's Instagram page on Friday.

In the first picture, Kourtney was seen resting her head on the musician's lap as the couple paused for a photo while sitting on the floor. Barker held Rocky gently while propping him up next to his shoulder.

In another snap, Kourtney was seen gently holding her seven-week-old son in her arms as she lovingly looked down at him while breastfeeding.

Early last month, on November 1, The Kardashians star gave birth to her baby boy – just two months after undergoing “horrific” fetal surgery to save her unborn son's life.

At the time of the baby announcement, both Barker and Kylie Jenner were spotted at Cedars-Sinai Medical Center in Los Angeles.

Rocky wasn't seen at the Kardashian-Jenner holiday party, but his name was on a life-size gingerbread house filled with sweet treats for the youngest partygoers.

The star guests had just as much fun as the Kardashian-Jenner sisters as Nicky Hilton shared a video on her Instagram of her sister Paris and Kim Kardashian sledding down a snowy hill.

There was clearly some Christmas magic as temperatures in Calabasas didn't drop below 42 degrees on Christmas Eve.

Paris and Kim couldn't help but smile and laugh as they walked through the fake snow.

The Kardashian-Jenner sisters were definitely in the festive spirit as every December the family puts on their best attire to celebrate Christmas with a huge party.

It has been a family tradition since 1978 and was only canceled once in 2020 due to rising Covid-19 cases.

“I think it's the first time since 1978 that we're not having a Christmas Eve party,” Khloe tweeted at the time.

The 2021 celebrations saw a significant decline as the emerging Omicron variant impacted the arrangements of the Kardashian-Jenner clan.

But in 2022, the reality star family's famous Christmas Eve party is back in full swing, decorated with even more glamor than before.

Last year, Kourtney hit the nail on the head as host, transforming her apartment with red Christmas trees, red balloons, and — you guessed it — red lights.

But that wasn't all this amazing party had to offer as there was a ball pit, balloon animals and even the chance to hang out with Santa.
