Kourtney Kardashian was not happy with the way things played out at her stepson’s birthday when an awkward moment arose.

This included a poor Diddy joke taking center stage out of nowhere, leaving her stunned and grossed out.

The party was hosted by her for Landon Barker and then all of a sudden, a joke was made about how he and his family showed up to a Diddy-themed birthday event in Los Angeles during the week’s start.

Kardashian who is his stepmom says she was mortified by his behavior but a source added how he was not informed about the poor dark joke beforehand. He referred to it as tasteless.

Another insider mentioned how Landon celebrated the 21st celebrations with a dinner at Nobu in Malibu that was thrown by the respective eldest Kardashian member and his dad, Travis Barker.

After the dinner was over, Landon and his good pals were seen at Harriet’s Rooftop Lounge in West Hollywood. This is where the servers were rolling out bottles of baby old with flashing lights. These were in reference to the 1000 bottles found during a raid at P. Diddy’s home during his arrest for trafficking.

It was later mentioned that someone saw him there in attendance and that it was held for Friends with Your Ex artist.
