Kourtney Kardashian didn’t show any of the telltale tired signs of having a newborn at home as she stepped out for her family’s annual star-studded holiday soiree on Sunday night.

The bright-eyed reality star, 44, rocked a sultry look – which didn’t include pants – at the annual Kardashian-Jenner Christmas Eve bash held this year at sister Kim’s estate.

Just seven weeks ago, the eldest Kardashian welcomed a 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 in the style of a robe and was cinched around her waist with a tie only revealing a peak at what was underneath … which wasn’t much.

The Poosh founder rocked a pair of sheer tights and a black bodysuit, opting out of pants or a skirt.

Kourtney glowed in social media videos from the party. Her raven tresses were slicked back in a snatched low ponytail with a side part and she stunned with her signature dramatic makeup.

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

Earlier this week on Wednesday, the Poosh founder took a big step and embarked on her ‘first day at the gym’ since welcoming baby Rocky.

She jumped to her Instagram stories to share that she was beginning to get back into a fitness regime, but reassured other mothers that ‘it’s not a race.’

While spending time on a treadmill, she typed out, ‘7 weeks postpartum: first day in the gym doing 30 minutes walking 3.0 12.0 incline…’

The mother-of-four added, ‘taking it easy, no rush no pressure mamas, your body is healing, it’s not a race.’

Kravis shared a first look of their baby boy in sweet, family holiday photos shared to the reality star’s Instagram page on Friday.

In the first picture, Kourtney could be seen resting her head on the musician’s lap as the couple paused for a photo while sitting on the floor. Barker gently held Rocky as he propped him up near his shoulder.

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

Earlier last month on November 1, The Kardashians star gave birth to their baby boy – just two months after she underwent a ‘terrifying’ fetal surgery to save her unborn son’s life.

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

Rocky wasn’t seen at the Kardashian-Jenner holiday bash but his name was included on top of a life size gingerbread house full of sweet treats for the youngest party guests.

The A-list guests were having as much fun as the Kardashian-Jenner sisters, as Nicky Hilton took to her Instagram to share a video of her sister Paris and Kim Kardashian sledding down a snowy hill.

It was clearly some Christmas magic as the temperatures in Calabasas didn’t dip below 42 degrees on Christmas Eve.

Paris and Kim couldn’t help but shares smiles and laughs as they made their way through the manufactured snow.

The Kardashian-Jenner sisters were certainly in the festive mood as every December, the family puts on their best gear to celebrate Christmas with a huge blowout party.

It’s been a family tradition ever since 1978, only being cancelled once in 2020 due to rising Covid-19 cases.

‘It’s the first time we will not be having a Christmas Eve party since 1978 I believe,’ Khloe tweeted at the time.

The celebrations in 2021 experienced a notable reduction due to the emerging Omicron variant impacting the Kardashian-Jenner clan’s arrangements.

However, in 2022, the renowned Christmas Eve party of the reality-star family returned in full swing, adorned with even more glamour than before.

Last year, Kourtney totally nailed it as the host, transforming her pad with red Christmas trees, red balloons, and—you guessed it—red lights.

But that’s not all this awesome bash had to offer, as there was a ball pit, balloon animals, and even a chance to hang out with Santa.
