The mother of three sported a pair of flared trousers and a very plunging top to the party.

But Kourtney seemed to be running late as her hair looked a bit disheveled as she arrived, keeping it tied in a messy ponytail. 

Also in attendance were Kim and Kanye West, who were also keen on making sure the runway favorite had a good pre-birthday meal.

Meanwhile, earlier that day Kendall appeared on TV with big sister Kourtney Kardashian to talk about their love lives.

During Ellen DeGeneres’ Show Me More Show on YouTube, the duo dished about what they find most attractive in a man and who their first crushes were during some rapid-fire questions.

While they raven haired beauties kept mum about their current romances, Kourtney, 38, opened up about her first ‘celeb crush’ as she revealed that she was so enamored with Leonardo DiCaprio, she wrote ‘Kourtney DiCaprio’ on all of her schoolwork. 

While Kourtney was dead set on being Mrs. DiCaprio, Kendall, 21, confessed her first celeb crush was Benny ‘The Jet’ Rodriguez from childhood favorite The Sandlot.

Kendall also revealed some of the secrets she used to keep from mom Kris, 61, during her rebellious teen years, admitting she used to sneak out to see an unidentified boyfriend on the regular.

‘I used to sneak out and say I was going to my friend’s, like a girlfriend’s house, but I really went to my boyfriend’s house and slept there every night,’ the beauty told her sister.

The pair also described what gives them the creeps, with Kourtney explaining she hates spiders while Kendall revealed she harbors a fear of ‘tiny little holes.’

‘That is very odd,’ responded the eldest Kardashian sister.

Fans got a better idea of what gets the social media starlet’s engines going as the duo completed the sentence ‘A man looks sexiest when he’s wearing…’

Kendall, who’s dating basketball player Blake Griffin, 28, quipped ‘tattoos.’ Lucky for her, her NBA star beau has a sizable collection of body art.

Kourtney went with a classic answer, choosing ‘Calvins’ as the ‘sexiest’ thing a man can wear. 

The mother-of-three’s answer makes more than enough sense, since she’s been going strong with model Younes Bendjima, 23, since the pair were first linked around spring 2017.

The model is even slated to appear on Kourtney’s beloved reality show Keeping Up With The Kardashians this season.

Before her current beau, Kourtney was with baby daddy Scott Disick, 34, for nine years, although the pair never married.

Since his split with the reality star, the socialite has moved on to dating model Sofia Richie, 19.

Meanwhile, Kendall’s relationship with Blake seems to be flourishing.

The starlet has become a constant court-side feature during the sportsman’s LA Clippers games since the NBA season kicked off in mid-October.

An insider seemed to confirm that the pair were official with Us Weekly late last week, explaining: ‘They’re legit. They’re a full-on couple.’

Before sparking things with Blake, Kendall was linked to rapper A$AP Rocky, but by the beginning of September it appeared that the relationship had run its course.

At the time of their parting, Us Weekly spoke with a source who revealed that the couple ‘weren’t really official’ and they ‘weren’t seeing each other a lot.’
