Kourtney Kardashian’s boyfriend Scott Disick attended a fashion show with Kendall and Kylie Jenner and apparently caused a ruckus after having too much to drink.

One of the models, Caroline D'Amore, a friend of the Kardashian family, flipped the bird to the Keeping Up with the Kardashians star while walking down the runway.

“Scott was being drunk and rude the whole night!” a source told Mail Online.

Disick was seen enjoying a drink while sitting in the front row with the Jenner sisters and a few friends. But the trouble started way before the show started, sources say.

Disick reportedly yelled at someone who stepped in front of him, “Get out of my light” and tried to pull fashion designer Cedric off the stage at the end.

“Cedric was fuming backstage and wanted him kicked out the show but the event publicist didn’t want to offend the Jenner girls,” said an onlooker.

TMZ reports after the show, Disick, Lil Twist and the Jenner sisters went to a 21-and-older nightclub, even though they’re only 16 and 17 years old.
