Kardashians finally reveal who pays for their annual Christmas party that has hosted Jennifer Lopez and Elon Musk

Khloe Kardashian candidly revealed that her family 'all equally split the cost' of the sumptuous Christmas Eve party they give every year.

The Kardashian-Jenners switch off on hosting, with last year's bash reportedly held at Kendall Jenner's $8.5 million Beverly Hills estate.

A fleet of celebrities have been guests at the fete over the years, including Jennifer Lopez, Alex Rodriguez, Paris Hilton, Elon Musk, Dave Chappelle, John Legend, Tyler The Creator and even Sean 'Diddy' Combs before his downfall.

Now Khloe, 41, has sat down with her mother Kris Jenner, 70 - who began the tradition in 1978 - to pull the curtain back on their Yuletide festivities.

The annual party goes back to when Kris was a Beverly Hills housewife married to future O.J. Simpson lawyer Robert Kardashian, the father of her four older children.

Kris hosted the beano every year until her children grew older and acquired so many friends that the guest list swelled to '2-300 people,' at which point the venue began 'rotating' between members of the family, she shared on Khloe in Wonderland. 

'I thought it was so much more fun, and then every time one of you took the reins and did it yourself -' Kris began, before Khloe cut her off.

'I won't take the reins. I don't want the reins. I don't want that many people in my home, and this year I was very proud of you for saving me,' Khloe told her mother.

Apparently a number of other Kardashian-Jenner homes were unavailable and Khloe's was suggested, only for Kris to leap in and table Kendall's as an alternative.

It was unclear whether Khloe and Kris - who live next door to each other - were referring to the latest Christmas party, which appeared to have been held at Kendall's house, or next week's.

Kris gushed that as her children grow older 'it's so exciting to see how you guys interpret your own Christmas Eve and how we can all enjoy each other every year.'

Khloe noted that the family will 'include each other on the theme' by way of 'a Pinterest board' and open invitation to 'the Mindy Weiss meetings.'

Weiss, 56, is an event planner who enjoys a long association with the Kardashians, notably as the orchestrator of Kylie Jenner's massive StormiWorld birthday carnivals for her daughter Stormi, seven, whom she shares with her rapper ex Travis Scott.

'Not everyone shows up and that's fine, but if you don't show up, you don't get a say-so,' Khloe said. 'Then you can't come to the third meeting and be like: "Oh, I don't like that." Nope. We've already have two meetings before. We've decided on X, Y and Z.'

Kris added in a sugary tone that she enjoys being able to 'share things with our friends,' such as Kim Kardashian's SKIMS products or Kendall's 818 tequila.

'You love a shameless plug,' Khloe teased her mother, and while Kris insisted: 'I love a party favor, that's what I love,' Khloe doubled down: 'You love a plug.'

Kendall, the possible hostess of this year's Christmas Eve bash, shed light on the upcoming knees-up in an interview last week.

'Last year, we did a smaller Christmas Eve party, and it was super lovely. Usually, they're kind of these blowouts for the last, like, since I was born,' she said. 

'But we're doing a smaller one again this year, and I'm really happy about it,' the supermodel told People. 'And so it'll be cozy vibes.'
