The event took place in Malibu and also saw Kim Kardashian all gussied up for the big celebration. Kardashian, 42, had on a yellow button-up cardigan and black mini skirt with platform heels.

This will be Kourtney’s fourth child. She already has Mason, Penelope and Reign.

This comes after Khloe got candid about her ‘skin cancer journey’ after her ‘rare’ melanoma diagnosis in an assortment of Instagram stories uploaded on Tuesday.

The Good American founder, 39, who recently transformed into Britney Spears to recreate her 2003 Pepsi interview, notably removed a tumor that left an indention on one side of her face – which she has begun to fill.

In October 2022, the TV personality took to social media to explain that bandages on her face were due to an ‘immediate operation’ to remove a cancerous bump which turned out to be melanoma.

In the latest update to her fans and followers, Khloe uploaded a snap as she posed with doctors from 7Q Spa that have helped fill the indention.

‘My Armenian Tribe. Master L has been helping me with my indention on my cheek from the tumor I had removed and she has done WONDERS!!!’

‘It will always be something we have to fill due to the mass but she has a magic wand if you ask me,’ the businesswoman continued.

Khloe then talked about her diagnosis and penned in a separate slide, ‘For those who do not know I had a skin cancer scare on my face.’

She called Beverly Hills surgeon, Dr. Garth Fisher, her ‘angel’ and added that he ‘is out of this world fabulous!’

‘Not only did he remove the tumor and made sure that I am completely cancer free but he did such a f***ing stellar job on making my scar as small and beautiful as possible. Thank you so much, Garth! You know I adore you.’

The mother of two shared a throwback snap of the spot on her face that she had assumed had been a stubborn pimple for months – but later discovered was cancerous.

‘We started here. This small spec of as melanoma…Yes that tiny dot that I thought was a pimple for almost a year.’ The star then showed the aftermath of the removal of the tumor which was stitched up on her cheek.

The reality star explained, ‘I know this looks crazy and pretty massive, which it was, but for all good reason @garthmd made sure to protect the stitches and make sure everything was flat as possible so there was no stretching of the scar, incision area, and we tried to avoid keloiding as much as possible…He’s just the best.’

Khloe then uploaded a close-up selfie to show the indention on her cheek after removing the cancerous bump.

She explained to her followers that, ‘because we had to remove a tumor from my cheek, I was left with an indention.’

‘I am definitely not complaining because I would rather have an indention than melanoma any day.’

Kardashian then expressed her gratitude ‘to all the doctors who helped and continue to help me with my skin cancer journey.’

She shared another close-up image of her indention and revealed that she ‘waited over nine months to get this filled by the way. Patience is everything and of course we have to make sure medically everything is safe.’

The Good American founder then uploaded a collage of photos that had been taken during her journey and encouraged her fans to, ‘Be consistent with your skin cancer checks! No one is exempt.’

She also gave a few before-and-after shots upon getting fillers into her indention after removing the tumor.

‘I look insane in these pics but I’m just so happy that my face is slowly coming back together ha! I don’t even know how else to word this.’
