Kourtney Kardashian ‘mortified’ by sick Diddy gag during Travis Barker’s son Landon’s 21st birthday bash

Kourtney Kardashian did not find the inappropriate Diddy joke at her stepson’s birthday party amusing in the slightest.

The POOSH founder, 45, attended Landon Donovan’s 21st birthday celebration at Nobu Malibu on Wednesday, hosted by her husband, Travis Barker. During the event, servers carried bottles of baby oil with flashing lights, referencing the 1,000 bottles of baby oil allegedly found in Diddy’s home during his arrest on sex trafficking charges.

‘Kourtney was not in on this joke at all and was mortified when she realized what was happening,’ a source exclusively told DailyMail.com on Friday.

‘She wanted to leave because she was afraid of being associated with this joke. But it was too late, and she confronted Travis. He claimed it wasn’t his idea either, but they both knew how distasteful it was,’ the insider added.

‘They were just really hoping it wouldn’t go public. Landon made a mockery of something very serious at a time when the family is keen to distance themselves from Diddy,’ the source claimed, add that it has ’caused tensions.’

DailyMail.com has reached out Kardashian and Barker’s representatives for comment. 

The family misstep is unexpected, as Kourtney and Travis have been successfully blending their households since their wedding in May 2022.

Kourtney shares Mason, Penelope, and Reign with her ex, Scott Disick, while Travis is father to son Landon, daughter Alabama, and stepdaughter Atiana De La Hoya with Shanna Moakler.

In November, Kourtney and Travis welcomed their own son Rocky into the family.

At Landon’s 21st birthday party on Friday, the DJ hyped up the crowd, shouting, ‘We’re getting really freaky tonight. We’re getting Diddy freaky tonight.’

The reference to Diddy’s infamous ‘Freak-Offs, drug-fueled sex parties central to the federal case against him, sparked immediate controversy.

Though it’s unclear whether Blink-182 drummer Travis Barker had any involvement in the inappropriate jokes, fans have still labeled them as ‘insensitive and gross.’

Prior to partying with his pals, the newly legal drinker had dinner at the celeb-friendly sushi spot with his dad and step-mom Kourt.

Earlier in the day, Travis shared a slideshow of images of his oldest son from throughout his life on Instagram.

‘So proud of the man you’ve become and everything you’ve set out to accomplish and did. You are the best son and brother anyone could ask for. I love you always and forever my boy and cherish every moment with you.’

Kourtney commented on the post, sharing a simple, ’21!!’ with a heat emoji.

Landon’s sister Atiana De La Hoya wrote, ‘Landon, the best sister,’ while Landon replied to his father, ‘I love you!’

Meanwhile, Combs continues to be a force in the entertainment world, maintaining his influence even while incarcerated.

The 54-year-old music mogul is currently in federal custody amid serious federal sex trafficking charges and various civil lawsuits.

The bottles were a clear and tasteless reference to the 1,000 bottles of baby oil that were allegedly found inside of Diddy ‘s home when he was arrested on sex trafficking charges

According to a source speaking to People on Monday, his reputation continues to evoke fear among many in the industry, reflecting the enduring reach of his influence.

‘He’s so powerful. Everyone was afraid to cross him,’ the insider claimed. ‘Even though he’s behind bars now, he’s still so powerful. We all knew it even back then.’

The source added: ‘He’s incredibly smart, he knows a lot of people, and he’s helped a lot of people — so a lot of people owe him. He knows that.’ 

The insider went on to say that Diddy’s obsession with control was often attributed to his creative genius.
